The 28°C PCM: A High-Performance Material With The Remarkable Ability To Absorb Or Release A Substantial Quantity Of Heat During The Phase Change Process, Ensuring Efficient Thermal Regulation

Basic attributes:
1. Appearance

• It is usually a transparent liquid, and it remains liquid when the temperature is higher than 28°C.

2. Phase change temperature

• About 28.4 °C, at this temperature the material changes from liquid to solid or vice versa.

3. Phase change enthalpy

• About 220 to 240 joules per gram, this value indicates the amount of heat that the material can absorb or release during the phase change process.

4. Density

• About 0.78 grams per milliliter, this density index helps to calculate the heat storage capacity in a specific volume.

Fields of application:
1. Textile

• By integrating phase change materials into fibers, textiles that can adjust the warmth retention performance according to the ambient temperature are manufactured.

2. Building materials

• Phase change materials can be integrated into building materials such as gypsum board or walls, and their heat storage capacity can be used to naturally adjust the indoor temperature, so as to achieve energy-saving effects.

3. Microcapsule core material

• The phase change material is encapsulated by microcapsule technology, which can be widely used in occasions that require fine temperature control, such as heat dissipation of electronic devices.

Special features:
1. Supercooling and phase separation

• Some organic phase change materials do not have the problem of supercooling and phase separation, and their performance is relatively stable, which makes them more reliable in practical applications.

2. Thermal conductivity

• Although PCMs have high latent heat storage capacity, they generally have low thermal conductivity, which may limit their application in situations where rapid heat transfer is required.

3. Shape stability and durability

• New types of phase change materials are being developed to improve the thermal conductivity, shape stability and durability of the material, which are essential for long-term use and to increase the rate of charge and discharge.

4. Enhanced heat transfer technology

• In order to improve the heat transfer efficiency of phase change materials, researchers have explored a variety of enhanced heat transfer technologies, such as adding fins, nanoparticles, or using external fields and rotation.

The status quo of the industry:
1. R&D and production

• Some companies, such as Guangzhou Zhongjia New Material Technology Co., Ltd., focus on the R&D and production of phase change materials, which can provide high-purity phase change materials that meet different needs, and have passed ISO 9001 certification.

2. Wide application

• The products of these companies are widely used in energy-saving buildings, cold chain transportation, heat storage and other fields to promote the commercialization and large-scale application of phase change materials.

Trends:
1. Composite phase change materials

• In view of the problem that simple phase change materials are easy to leak, researchers prepare composite phase change materials through porous material adsorption or microcapsule encapsulation technology, so as to improve the stability and application range of the materials.

2. Research on low-temperature phase change energy storage materials

• The academic community has conducted in-depth research on low-temperature phase change energy storage materials, including the basic characteristics of materials, classification, and applications in temperature regulation and heat storage.

3. Future prospects

• The future development direction includes improving the thermal conductivity of phase change materials, extending the service life, reducing costs and expanding new application fields.
