Research progress on gypsum-based composite phase change energy storage materials
Building energy consumption,industrial energy consumption and traffic energy consumption are main ways of energy consumption,of which building energy consumption accounts for about 40%.The continuous rise in building energy consumption will increase carbon emissions and accelerate the fossil energy consumption.Therefore,how to improve the thermal insulation and energy saving performance of building materials has gradually become a research hotspot in the field of building materials.Heat storage technology can reduce building energy consumption as well as environmental pollution.Phase change energy storage material exhibits excellent heat storage and release capacity,which is important in achievement of thermal energy storage and temperature control,and shows broad application prospects in the field of building energy conservation.Herein,the research progress on gypsum-based composite phase change energy storage materials was introduced.Gypsum-based organic phase change materials and gypsum-based composite phase change materials were then analyzed and summarized,followed by description on the preparation methods and mechanisms of gypsum-based composite phase change energy storage materials,such as impregnation method,porous material adsorption method and microcapsule method,as well as the influence factors.Finally,the research directions of gypsum-based phase change energy storage materials were discussed.
