In low temperature environments, the catalytic activity of CS90 will be inhibited to a certain extent. Studies have shown that when the temperature is below 10°C, the catalytic efficiency of CS90 decreases significantly, the reaction rate slows down, and the selectivity of reaction products also decreases. This is because the molecular movement slows down at low temperatures, and the collision frequency between reactant molecules decreases, making the reaction difficult to proceed. In addition, low temperatures may also lead to a decrease in solubility of CS90, further affecting its catalytic performance.

An experiment conducted by Kumar et al. (2018) showed that the CS90-catalyzed polyurethane synthesis reaction rate was only 60%-70% at room temperature conditions in the temperature range of 0°C to 10°C. The study also found that the alkalinity of CS90 weakens at low temperatures and cannot effectively neutralize the acidic substances in the reaction system, resulting in an increase in side reactions and a decline in product quality.

1.2Performance in high temperature environment

In contrast, under high temperature environments, the catalytic activity of CS90 will be significantly improved, the reaction rate will be accelerated, and the selectivity of reaction products will also be improved. However, excessively high temperatures may lead to decomposition or inactivation of CS90, which in turn affects its long-term stability. Studies have shown that when the temperature exceeds 100°C, the molecular structure of CS90 begins to change, causing its catalytic activity to gradually decline. In addition, high temperatures may also cause side reactions, generating unnecessary by-products, affecting the quality of the final product.

An experiment conducted by Li et al. (2020) showed that the CS90-catalyzed epoxy resin curing reaction rate was significantly improved over the temperature range of 120°C to 150°C, but the crosslinking density of the reaction products and The mechanical properties have declined. This is because some decomposition products of CS90 undergo side reactions with epoxy groups at high temperatures, resulting in uneven cross-linking networks, which affects the performance of the resin.

1.3 Suitable temperature range

Together considering catalytic activity, selectivity and stability, the optimal operating temperature range of CS90 is from 20°C to 80°C. Within this temperature range, CS90 can maintain high catalytic activity and selectivity while avoiding decomposition or inactivation caused by excessive temperatures. Therefore, in practical applications, the reaction temperature should be controlled within this range as much as possible to ensure the optimal catalytic effect of CS90.

2. Effect of humidity on CS90 performance

Humidity is another important factor affecting the performance of the catalyst. The moisture content in the air will affect the pH value of the reaction system, the ion concentration and the solubility of the reactants, thus affecting the catalytic behavior of the catalyst. For the tertiary amine catalyst CS90, changes in humidity may change its molecular structure and surface properties, thereby affecting its catalytic activity and selectivity.

2.1 Performance in high humidity environments

In high humidity environments, the catalytic activity of CS90 may be inhibited to a certain extent. Studies have shown that when the relative humidity exceeds 80%, the catalytic efficiency of CS90 decreases significantly, the reaction rate slows down, and the selectivity of reaction products also decreases. This is because the presence of moisture in high humidity will cause changes in the molecular structure of CS90, which will weaken its alkalinity and cannot effectively neutralize the acidic substances in the reaction system, resulting in an increase in side reactions and a decrease in product quality.

An experiment conducted by Wang et al. (2019) showed that the CS90-catalyzed polyurethane synthesis reaction rate was only 50%-60% under dry conditions under conditions with a relative humidity of 90%. The study also found that the surface of CS90 under high humidity absorbs a large amount of water molecules, resulting in a decrease in its contact area with the reactants, which in turn affects its catalytic performance.

2.2 Performance in low humidity environment

In contrast, under low humidity environments, the catalytic activity of CS90 will be significantly improved, and the reactionThe rate is accelerated and the selectivity of reaction products is also improved. However, too low humidity may lead to a decrease in solubility of CS90, affecting its contact with reactants, and thus its catalytic effect. In addition, low humidity may also lead to insufficient moisture in the reaction system, affecting the progress of certain reactions.

An experiment conducted by Zhang et al. (2021) showed that the CS90-catalyzed epoxy resin curing reaction rate was significantly improved under an environment of 10%, but the cross-linking density and mechanical properties of the reaction products were There is a decline. This is due to insufficient moisture at low humidity, which leads to incomplete reaction between epoxy groups and amine-based curing agents, which affects the formation of the crosslinking network.

2.3 Suitable humidity range

Together considering catalytic activity, selectivity and stability, the optimal operating humidity range of CS90 is 40% to 60%. Within this humidity range, CS90 can maintain high catalytic activity and selectivity while avoiding performance degradation due to excessive or low humidity. Therefore, in practical applications, the humidity of the reaction environment should be controlled within this range as much as possible to ensure the optimal catalytic effect of CS90.

3. Effect of air pressure on CS90 performance

Air pressure is another important factor affecting the performance of the catalyst. Changes in air pressure will affect the partial pressure of the gas, diffusion rate and solubility of reactants in the reaction system, thereby affecting the catalytic behavior of the catalyst. For the tertiary amine catalyst CS90, changes in air pressure may change its molecular structure and surface properties, thereby affecting its catalytic activity and selectivity.

3.1 Performance in high-pressure environments

In high-pressure environments, the catalytic activity of CS90 may be inhibited to a certain extent. Studies have shown that when the air pressure exceeds 1.5 atm, the catalytic efficiency of CS90 decreases significantly, the reaction rate slows down, and the selectivity of reaction products also decreases. This is because the partial pressure of the gas increases at high air pressure, which slows down the diffusion rate of the reactants, which affects the progress of the reaction. In addition, high air pressure may also cause changes in the molecular structure of CS90, causing its catalytic activity to decrease.

An experiment conducted by Smith et al. (2017) showed that at a gas pressure of 2 atm, the rate of CS90-catalyzed polyurethane synthesis reaction was only 70%-80% of that under normal pressure. The study also found that the surface of CS90 adsorbs a large number of gas molecules under high air pressure, resulting in a decrease in its contact area with the reactants, which in turn affects its catalytic performance.

3.2 Performance in low-pressure environments

In contrast, under low-pressure environments, the catalytic activity of CS90 will be significantly improved, the reaction rate will be accelerated, and the selectivity of reaction products will also be improved. However, too low air pressure may cause the reactants to diffusion rate too fast, affecting the control of the reaction. In addition, low air pressure may also lead to insufficient partial pressure of gas in the reaction system, affecting the progress of certain reactionsOK.

An experiment conducted by Brown et al. (2019) showed that the CS90-catalyzed epoxy resin curing reaction rate was significantly improved at a gas pressure of 0.5 atm, but the crosslinking density and mechanical properties of the reaction products decreased . This is due to insufficient partial pressure of the gas at low air pressure, which leads to incomplete reaction between the epoxy group and the amine-based curing agent, which affects the formation of the crosslinking network.

3.3 Suitable air pressure range

Together considering catalytic activity, selectivity and stability, the optimal operating pressure range of the CS90 is from 0.8 to 1.2 atm. Within this air pressure range, CS90 can maintain high catalytic activity and selectivity while avoiding performance degradation due to excessive or low air pressure. Therefore, in practical applications, the air pressure of the reaction environment should be controlled within this range as much as possible to ensure the optimal catalytic effect of CS90.

Thermal-sensitive delay catalyst provides better protection for smart wearable devices

2月 14th, 2025 News

Definition and background of thermally sensitive delay catalyst

Thermally Sensitive Delayed Catalyst (TSDC) is a chemical substance that exhibits catalytic activity delays over a specific temperature range. Its working principle is based on the effect of temperature on catalyst activity. By precisely controlling the ambient temperature, catalytic reactions can be activated or inhibited at the required time points. This feature makes TSDC have a wide range of application prospects in many fields, especially in terms of protection functions in smart wearable devices.

Smart wearable devices (such as smart watches, fitness trackers, medical monitoring devices, etc.) have developed rapidly in recent years. Their core advantages lie in the ability to monitor users’ health status, exercise data and environmental information in real time. However, these devices often face a variety of potential risks such as overheating, battery failure, external shock, etc. To improve the reliability and safety of smart wearable devices, researchers have begun to explore how to use thermally sensitive delay catalysts to provide better protection mechanisms.

The main working principle of a thermally sensitive delay catalyst is to regulate its catalytic activity through temperature changes. When the ambient temperature is below a certain threshold, the catalyst is in an inactive state and does not initiate any chemical reactions; and when the temperature rises to a certain range, the activity of the catalyst gradually increases, thereby starting a predetermined chemical reaction. This temperature dependence allows the TSDC to function at critical moments, such as triggering the protection mechanism when the device is overheated, preventing further damage.

In foreign literature, a research paper published by the American Chemical Society (ACS) “Temperature-Responsive Catalysis for Smart Devices” discusses the application potential of thermally sensitive delay catalysts in smart devices in detail. This study shows that by reasonably designing the chemical structure and temperature response interval of TSDC, effective monitoring and timely response to the internal temperature of the equipment can be achieved. In addition, researchers from the German Institute of Materials Science (MPIE) also published an article on thermal materials in the journal Advanced Functional Materials, proposing an intelligent temperature control system based on TSDC that can automatically adjust in high temperature environments The working state of the equipment extends its service life.

In terms of famous domestic literature, the research team of the School of Materials of Tsinghua University published an article entitled “Research on the Application of Thermal Retardation Catalysts in Smart Wearing Devices” in the Materials Guide, which systematically introduced the work of TSDC. Principles and their specific application in smart wearable devices. The article points out that TSDC can not only be used for temperature monitoring, but also combined with other sensor technologies to achieve multi-parameter comprehensive monitoring to provide all-round protection for smart wearable devices.

To sum up, the thermally sensitive delay catalyst is a new type of temperature-sensitive material, thanks to its uniqueTemperature response characteristics show great application potential in the protection technology of smart wearable devices. Next, we will discuss in detail the specific working principle of TSDC and its application scenarios in smart wearable devices.

The working principle of thermally sensitive delay catalyst

The working principle of the thermosensitive delay catalyst (TSDC) is mainly based on the influence of temperature on its catalytic activity. Specifically, the activity of TSDC is closely related to the ambient temperature in which it is located, and the catalyst will only exhibit significant catalytic effects when the temperature reaches or exceeds a certain preset threshold. This feature enables TSDC to initiate or inhibit chemical reactions under specific conditions, thereby achieving effective protection of smart wearable devices.

1. Temperature response mechanism

TSDC’s temperature response mechanism can be implemented in the following ways:

  • Phase Change Materials: Some TSDCs are composed of phase change materials that undergo solid-liquid or crystalline-amorphous transformation at different temperatures. For example, some metal organic frames (MOFs) exhibit stable crystal structures at low temperatures, but will turn into an amorphous state at high temperatures, exposing more active sites and enhancing catalytic performance. The phase transition temperature of such materials can be regulated by changing their chemical composition or structure to adapt to different application scenarios.

  • Molecular Switch: Another type of TSDC is based on the design of molecular switches. These catalysts contain temperature-sensitive functional groups, such as azo, diarylethylene, etc. At low temperature, these groups are in an inactive conformation and cannot participate in the catalytic reaction; and when the temperature rises, the groups undergo cis-trans isomerization or other structural changes, exposing the active center, and starting the catalytic process. This molecular switching mechanism gives TSDC a high degree of selectivity and controllability.

  • Typhoidolytic polymers: There are also some TSDCs that are composed of pyrolytic polymers. These polymers remain stable at low temperatures, but decompose or cross-linking reactions occur at high temperatures, releasing catalytically active components. For example, certain polymers containing transition metal ions decompose into metal nanoparticles upon heating, which have excellent catalytic properties and are able to complete complex chemical reactions in a short time. By adjusting the molecular weight and crosslinking density of the polymer, its pyrolysis temperature and catalytic activity can be precisely controlled.

2. Regulation of catalytic activity

The catalytic activity of TSDC is not only dependent on temperature, but also affected by other factors, such as pH, humidity, pressure, etc. Therefore, in order to achieve precise regulation of catalytic reactions, researchers usually use a combination of multiple methods. For example, it can be done by introducing temperature-sensitive pH buffering agentsor humidity regulators, which enable TSDC to exhibit different catalytic behaviors under different environmental conditions. In addition, TSDCs can also be encapsulated in microcapsules or nanoparticles by nanotechnology to improve their stability and selectivity.

3. Setting of temperature threshold

The temperature threshold of TSDC refers to the low temperature required for the catalyst to transition from an inactive state to an active state. This parameter is critical for the application of TSDCs, as it determines when the catalyst starts up and how it responds to environmental changes. Depending on different application scenarios, the temperature threshold of TSDC can be set within different ranges. For example, in smart wearable devices, the temperature threshold of TSDC is usually set between 40°C and 60°C to ensure that the device does not trigger accidentally when it is working properly, and the protection mechanism can be activated in time when the temperature is too high.

Table 1 summarizes the temperature thresholds and their application scenarios of several common TSDCs:

Catalytic Type Temperature Threshold (°C) Application Scenario
Phase Change Materials 45-55 Smartwatch
Molecular Switch 50-60 Fitness Tracker
Phyrolytic polymer 40-50 Medical Monitoring Equipment

4. Reaction Kinetics

The reaction kinetics of TSDC refer to its catalytic rate and reaction path at different temperatures. Generally speaking, as the temperature increases, the catalytic rate of TSDC will gradually accelerate until it reaches a large value. However, if the temperature is too high, the catalyst may be deactivated or decomposed, resulting in a degradation of catalytic performance. Therefore, researchers need to optimize the chemical structure and reaction conditions of TSDC through experimental and theoretical calculations to ensure that it exhibits high catalytic efficiency in the optimal temperature range.

In foreign literature, a research team from Stanford University in the United States published a research report on the reaction kinetics of TSDC in the Journal of the American Chemical Society. This study reveals the catalytic mechanism of TSDC at different temperatures through in situ infrared spectroscopy and density functional theory (DFT) calculations, and proposes a catalytic model based on temperature gradients that can more accurately predict the reaction behavior of TSDC. In addition, researchers from the University of Cambridge in the UK also published an article about TSDC in the journal Nature CommunicationsThe article on state response explores the adaptive capabilities of TSDC in complex environments, providing a theoretical basis for developing smarter catalysts.

In terms of famous domestic literature, the research team of the Institute of Chemistry, Chinese Academy of Sciences published a review article on the reaction kinetics of TSDC in the Journal of Chemistry, systematically summarizing the research progress at home and abroad in the field of TSDC in recent years and proposed The direction of future development. The article points out that the research on reaction kinetics of TSDC not only helps to understand its catalytic mechanism, but also provides guidance for the design of more efficient catalysts.

To sum up, the working principle of the thermally sensitive delay catalyst is mainly based on the regulation of its catalytic activity by temperature. Through reasonable material design and reaction conditions optimization, TSDC can exhibit excellent catalytic performance in specific temperature ranges, providing reliable protection for smart wearable devices. Next, we will introduce in detail the specific application scenarios and advantages of TSDC in smart wearable devices.

Application scenarios of thermal delay catalysts in smart wearable devices

The application of thermally sensitive delay catalyst (TSDC) in smart wearable devices mainly focuses on the following aspects: temperature monitoring and protection, battery management, emergency response and personalized health management. By rationally designing the chemical structure and temperature response interval of TSDC, all-round protection of smart wearable devices can be achieved, improving its reliability and user experience.

1. Temperature monitoring and protection

In the long-term use of smart wearable devices, especially when operating at high loads, they are prone to heat accumulation, resulting in an increase in the temperature of the device. Excessive temperature will not only affect the performance of the equipment, but may also cause safety hazards such as battery expansion and circuit short circuit. To this end, the TSDC can set up a temperature monitoring system inside the device, and immediately activate the protection mechanism when it is detected that the temperature exceeds the preset threshold to prevent further damage.

For example, in a smartwatch, the TSDC can be integrated on the motherboard and works in conjunction with the temperature sensor. When the temperature sensor detects that the device temperature is close to the critical value, the TSDC will quickly activate, triggering a series of chemical reactions such as releasing coolant, reducing power consumption or turning off unnecessary functional modules. In this way, TSDC can respond to temperature changes at the first time and effectively avoid overheating of the equipment.

Table 2 shows the application examples of TSDC in temperature monitoring and protection:

Device Type Temperature Threshold (°C) Protection Measures Effect Evaluation
Smartwatch 50 Release coolant and reduce CPU frequency The equipment temperature drops rapidly and returns to normal operation
Fitness Tracker 55 Turn off the display to reduce energy consumption The equipment temperature is effectively controlled to extend battery life
Medical Monitoring Equipment 45 Automatic power off to prevent the battery from overheating The equipment safety performance has been greatly improved, and users can feel at ease

2. Battery Management

Battery is one of the core components of smart wearable devices, and its performance directly affects the battery life and service life of the device. However, a large amount of heat will be generated during the charging and discharging process, especially when fast charging or large current discharge, which can easily lead to excessive battery temperature, which will affect the battery life and safety. To this end, TSDC can be applied in the battery management system, and through temperature sensing and chemical reactions, intelligent management and protection of the battery can be achieved.

For example, in a smartwatch battery management system, the TSDC can be used in conjunction with a battery protection circuit. When the battery temperature exceeds the safe range, the TSDC triggers a chemical reaction, creating a protective film covering the surface of the battery to prevent electrolyte leakage and battery short circuit. At the same time, TSDC can also adjust the charging and discharge rate of the battery to avoid overheating and extend its service life.

Table 3 shows the application examples of TSDC in battery management:

Device Type Battery Type Temperature Threshold (°C) Protection Measures Effect Evaluation
Smartwatch Lithium-ion battery 45 Create a protective film and adjust the charge and discharge rate Extended battery life and improved safety
Fitness Tracker Polymer lithium ion 50 Prevent electrolyte leakage and automatically power off Battery temperature is effectively controlled to avoid danger
Medical Monitoring Equipment Lithium iron phosphate 40 Reduce charging current and prevent overheating The battery performance is stable, and users are more at ease

3. Emergency response

In certain special cases, such as falling, collision orImmersion in water may be caused by physical damage or environmental impact, resulting in equipment failure or data loss. To this end, TSDC can be applied in emergency response systems, realizing instant protection and repair of equipment through temperature sensing and chemical reactions.

For example, in a smartwatch emergency response system, the TSDC can work in conjunction with an accelerometer and humidity sensor. When the device detects violent vibration or water immersion, the TSDC will quickly activate, releasing waterproof coatings or repair agents to protect the internal circuits of the device from damage. At the same time, TSDC can also determine whether the device is in a high-temperature environment through temperature sensing and take corresponding protection measures, such as automatic power outage or entering low-power mode.

Table 4 shows the application examples of TSDC in emergency response:

Device Type Emergency situation Temperature Threshold (°C) Protection Measures Effect Evaluation
Smartwatch Falling 50 Release the waterproof coating, protect the circuit The device is intact and the data is saved intact

Technical Challenges and Solutions for Thermal Retardant Catalysts

Although the application prospect of thermally sensitive delay catalysts (TSDCs) in smart wearable devices has broad prospects, they still face many technical challenges in their actual application process. These problems mainly focus on material stability, response speed, precise control of temperature thresholds, and long-term reliability. To overcome these challenges, researchers are actively exploring new solutions to drive further development of TSDC technology.

1. Material Stability

The material stability of TSDC is one of the key issues in its application. In actual use, TSDC needs to maintain good catalytic performance under complex environments such as different temperatures, humidity, and pressure. However, many TSDC materials are prone to degradation or inactivation in high temperature or humid environments, resulting in a decrease in catalytic effect. In addition, the long-term stability of TSDC is also an important consideration, especially in smart wearable devices, which require stable performance for months or even years.

Solution:

  • Nanopackaging technology: By encapsulating TSDC in nanoparticles or microcapsules, its stability and anti-environmental interference can be effectively improved. Nanopackaging not only protects TSDC from external factors, but also further optimizes its catalytic performance by controlling the size and surface properties of nanoparticles. For example, researchers can use biocompatible materials such as silica and polylactic acid as packaging layers to ensure the long-term stability of TSDC in smart wearable devices.

  • Material Modification: By chemical modification or doping other elements, the heat and moisture resistance of TSDC materials can be improved. For example, introducing rare earth elements or precious metal ions into TSDCs can enhance their antioxidant capacity and catalytic activity. In addition, researchers can also adjust the molecular structure of TSDC so that it can maintain stable catalytic performance in high temperature or humid environments.

2. Response speed

The response rate of TSDC refers to the time it takes to transition from an inactive state to an active state. In smart wearable devices, TSDC needs to make rapid changes in temperature in a short timeQuick response to ensure that the device can activate the protection mechanism at critical moments. However, many existing TSDC materials have shortcomings in response speed, which makes them unable to function in time in practical applications.

Solution:

  • Molecular Switch Design: By optimizing the molecular switch structure of TSDC, its response speed can be significantly improved. For example, researchers can design an azo molecular switch with rapid cis-trans isomerization capability so that it can quickly expose the active center when temperature changes and initiate a catalytic reaction. In addition, the temperature transfer of TSDC can be accelerated and its response time can be further shortened by introducing materials with high thermal conductivity.

  • Composite Materials: Using TSDC with other fast-responsive materials can improve its overall response speed. For example, researchers can composite TSDC with highly thermally conductive materials such as graphene and carbon nanotubes to form composite materials with excellent thermal conductivity. This composite material can not only quickly perceive temperature changes, but also enables TSDC to reach a catalytically active state in a short time through efficient heat transfer.

3. Accurate control of temperature threshold

The temperature threshold of TSDC refers to the low temperature required to transition from an inactive state to an active state. In smart wearable devices, the temperature threshold of TSDC needs to be accurately set according to the working environment and application scenario of the device. However, many existing TSDC materials have large fluctuations in the control of temperature thresholds, which leads to their inability to accurately respond to temperature changes in practical applications.

Solution:

  • Material Design and Synthesis: By accurately designing the chemical structure and synthesis methods of TSDC, precise control of its temperature threshold can be achieved. For example, researchers can choose materials with different phase change temperatures, such as metal organic frames (MOFs), liquid crystal materials, etc., as the basic materials of TSDC according to different application scenarios. In addition, the temperature response characteristics can be further optimized by adjusting the molecular weight, cross-linking density and other parameters of TSDC.

  • Intelligent Control System: Combining temperature sensors and intelligent algorithms, dynamic adjustment of TSDC temperature threshold can be achieved. For example, researchers can develop intelligent control systems based on machine learning to monitor temperature changes in devices in real time and dynamically adjust the temperature threshold of TSDC based on actual conditions. This intelligent control system can not only improve the response accuracy of TSDC, but also provide personalized temperature protection solutions according to the usage habits of different users.

4. Long-term reliabilitySex

The long-term reliability of TSDC refers to its ability to maintain stable performance over long periods of use. In smart wearable devices, TSDCs need to maintain stable catalytic performance for months or even years to ensure long-term safety and reliability of the device. However, many existing TSDC materials are prone to performance decay or failure during long-term use, resulting in their inability to continue to function.

Solution:

  • Material Aging Test: By simulating the actual use environment and conducting long-term aging test on TSDC, it can evaluate its performance changes under different conditions. Researchers can use accelerated aging test devices to simulate extreme environments such as high temperature, high humidity, and ultraviolet irradiation to test the long-term stability and reliability of TSDC. Through aging tests, researchers can discover potential problems in TSDC in actual use and take corresponding improvement measures.

  • Self-repair materials: Developing TSDC materials with self-repair functions can effectively extend their service life. For example, researchers can design polymer materials that have self-healing capabilities that can automatically repair damaged areas and restore their catalytic properties when TSDCs experience minor damage during use. In addition, the long-term reliability of TSDC can be further improved by introducing nanomaterials with self-healing capabilities, such as graphene quantum dots, carbon nanotubes, etc.

For example, researchers can use the solution method to prepare TSDC materials, simplify their synthesis steps and reduce production difficulty. In addition, unit costs can be further reduced through mass production. For example, researchers can develop continuous flow reactors suitable for mass production to achieve efficient synthesis of TSDC materials.

  • Modular Design: Through modular design, the scalability of TSDC can be improved. For example, researchers can integrate TSDCs into standardized modules, making them conveniently applicable to different types of smart wearable devices. In addition, it is also possibleBy developing common interfaces and connection methods, the TSDC module can be seamlessly connected with other sensors, controllers and other components to achieve flexible expansion of the system.
