Phase change materials: Opening a new era of energy management

In today's rapid development of science and technology, a magical material is quietly changing our lives - phase change materials.

Like an intelligent energy manager, it plays a key role in many fields by virtue of its unique nature.

01 Revealing phase change materials

PCM - Phase Change Material is a material that changes its physical state with temperature and absorbs or releases a large amount of energy in the process.

The absorption and release of this energy comes from the reorganization of its internal microstructure. Just like when ice melts into water, it absorbs heat, and when water solidifies into ice, it releases heat, but the power of the phase change material is more powerful and efficient.

02 Diverse families of phase change materials

-- Organic phase change materials

• Paraffin is a common organic phase change material, which will undergo solid-liquid phase change at a specific temperature.
• Organic phase change materials have many advantages, such as large latent heat of phase change, stable chemical properties, almost no supercooling phenomenon and small volume change when melting, so in the field of building energy conservation, it is often used to prepare thermal insulation materials to help buildings maintain comfortable temperatures in different seasons.

-- Inorganic phase change materials

• Crystalline hydrated salts are typical, such as sodium sulfate decahydrate. This kind of material has high enthalpy of phase change, large thermal conductivity and relatively low cost.
• However, the problems of supercooling and phase separation limit its application. In the field of solar energy storage, researchers try to overcome these problems by modifying it to make it better store solar heat.

-- Composite phase change materials

• In order to synthesize the advantages of various types of phase change materials, organic and inorganic phase change materials are combined by a specific process.
• For example, the combination of paraffin and bentonite not only improves the energy storage performance of the material, but also enhances its stability.
• This composite method makes up for the deficiency of a single material and makes the performance of phase change materials more excellent.

03 Wide range of applications

-- Construction field

• Integrate phase change materials into building materials, such as gypsum board, concrete, etc. In the hot summer, it can absorb excess heat in the room and prevent the indoor temperature from being too high.
• In the cold winter, it can release the stored heat and play a role in insulation. This not only improves indoor comfort, but also significantly reduces building energy consumption, helping to achieve green building goals.

-- Electronic equipment

• With the high degree of integration of electronic devices, the problem of heat dissipation becomes more and more serious.
• Phase change materials can be made into heat sinks or filled in the equipment, when the chip and other parts of the temperature rise, phase change materials quickly absorb heat and phase change, so as to effectively control the temperature of the equipment, ensure the stable operation of electronic equipment, extend the service life.

-- Cold chain logistics

• During the transportation of fresh items such as food, maintaining a low temperature environment is crucial.
• The cold storage agent made of phase change materials can maintain low temperature for a long time, without frequent replacement of the ice pack, ensuring the quality and safety of the goods, and providing strong support for the efficient operation of the cold chain logistics.
