Innovative 37°C Phase Change Microcapsules: A Revolutionary Solution To Substantially Improve The Energy Efficiency Of Buildings And Transform The Architectural Landscape

Composition and structure:

• It generally consists of an outer shell and a kernel. The shell is usually a polymer material with good stability and tightness, able to wrap the core material and prevent it from leaking. The inner core is a phase change material, which occurs when the temperature reaches 37°C.
• Below 37°C, the core may be in one state such as solid or liquid, and at temperatures above 37°C, it will change to another state (e.g. from solid to liquid or from liquid to gaseous, depending on the PCM used).

Performance characteristics:

1. Temperature sensitivity

• Its core feature is that it is sensitive to temperatures of 37°C. When the ambient temperature approaches or reaches 37°C, the phase change material of the core begins to absorb or release heat to achieve temperature regulation.
• For example, when the ambient temperature rises to 37°C, the phase change material absorbs heat and changes from one state to another, a process that can absorb a large amount of heat, thereby reducing the temperature of the surrounding environment and avoiding further temperature increases.
• Conversely, when the temperature drops, it releases heat according to the characteristics of the phase transition, keeping the ambient temperature relatively stable.

2. Stability and reliability

• Due to the protective effect of the outer shell, the phase change microcapsules are able to maintain the structural integrity during the phase change process without material leakage or changes in properties due to phase change.
• At the same time, it can maintain good performance in multiple phase change cycles, with high reliability and durability.

3. Size advantage

• Microcapsules generally have a smaller size, often at the micron level or even smaller. This small size allows them to disperse well in a variety of matrices, such as coatings, fibers, etc., without significantly adversely affecting the performance and appearance of the matrix.
• Moreover, the small size is also conducive to increasing the contact area between the microcapsule and the surrounding environment, and improving the efficiency of its temperature regulation.

Fields of application:

1. Biomedical field

• In terms of drug delivery, its phase change properties can be used to control drug release. The drug is encapsulated in microcapsules, and when the microcapsules are in the human body temperature (37°C) environment, the timing and speed of drug release are controlled according to the designed phase change mechanism to achieve precise drug treatment.
• For example, in the local treatment of some diseases, drug-loaded microcapsules can be delivered to the lesion site, and when the temperature reaches 37°C, the microcapsules undergo a phase change, releasing the drug, improving the therapeutic effect and reducing the systemic side effects of the drug.
• In tissue engineering, 37°C phase change microcapsules can be used as a smart material to regulate the temperature of the cell culture environment.
• For example, in the process of in vitro cell culture, when the temperature of the culture environment fluctuates, the microcapsules can absorb or release heat through phase transformation, providing a relatively stable temperature condition for the cells, which is conducive to the growth and differentiation of cells.

2. In the field of smart textiles

• It can be added to clothing fabrics to make smart textiles with temperature regulation. When the body temperature of the human body rises to about 37°C, the microcapsules absorb the heat, so that the surface temperature of the human body will not rise too quickly, bringing a cool feeling.
• When the body temperature of the human body drops, the microcapsules will release heat to keep the human body warm and improve the comfort of wearing.
• This kind of smart textile is especially suitable for outdoor sportswear, occupational protective clothing and other fields, which can meet people's needs for temperature regulation in different environments and activity states.

3. In the field of building energy efficiency

• The application of 37°C phase change microcapsules to building materials can improve the energy efficiency of buildings.
• For example, when it is added to wall paint or thermal insulation materials, when the indoor temperature is close to or reaches 37°C, the microcapsules undergo a phase change to absorb heat, reduce the indoor temperature, and reduce the energy consumption of refrigeration equipment such as air conditioners.
• When the temperature is low, the microcapsules can release heat and play a certain role in heat preservation, which helps to reduce the overall energy consumption of the building and achieve the goal of energy conservation and emission reduction.

4. The field of heat dissipation of electronic equipment

• For some temperature-sensitive electronic components, 37°C phase change microcapsules can be used as an effective heat dissipation material.
• When the temperature of the electronic components rises close to 37°C when they are working, the microcapsules absorb the heat to prevent the components from being damaged by excessive temperature, and ensure the normal operation and stability of the electronic equipment.
• At the same time, its good temperature regulation performance can prolong the service life of electronic components and improve the reliability of electronic equipment.
