TOP-X Composite phase change energy storage materials

The use of montmorillonite to encapsulate paraffin can not only effectively solve the problem of liquid phase leakage of paraffin, but also montmorillonite has stable chemical properties, non-toxic, low price and wide sources. And the composite phase change energy storage materials prepared from it have good economic benefits.


Composite phase change energy storage materials


Phase change energy storage materials are a class of substances that use the characteristics of energy absorption or release accompanied by their own phase changes to achieve energy storage and temperature regulation. Suitable commonly used phase change materials are usually paraffin (alkanes), fatty acids, polyethylene glycol, etc. Paraffin wax is the most commonly used solid-liquid phase change material, it has high latent heat of phase change (150kJ/kg~250 kJ/kg), no obvious subcooling phenomenon, non-corrosive, wide source, low price, etc., is a very promising phase change energy storage material. But it exists in the phase change process when the material changes from solid to liquid, often accompanied by liquid flow and leakage phenomenon. And the problems of easy to lead to corrosion are difficult to control well. To a large extent, it restricts its further application development.

Montmorillonite is a 2:1 layered aluminosilicate, which can exchange cations and external ions without destroying the basic structure of montmorillonite. So it gives montmorillonite special cation exchange and expansion properties, which has potential application prospects in the field of composite phase change energy storage. The use of montmorillonite to encapsulate paraffin can not only effectively solve the problem of liquid phase leakage of paraffin, but also montmorillonite has stable chemical properties, non-toxic, low price and wide sources. The composite phase change energy storage materials prepared from it have good economic benefits.
