Abstract: Phase change materials (PCMs) play an important role in solving the imbalance between energy demand and supply as they can absorb and release large amount of heat during phase change procedure.Therefore,using PCMs is an efficient way to substantially improve energy utilization and conserve waste heat.Composite PCMs have been extensively researched due to their stable chemical properties and great heat storage capacity.Preparation methods of the composite PCMs were mainly introduced,including the multi-porous substrate adsorption method,micro/nano encapsulation method,sol-gel method,polymer composite copolymerization and electrospinning method.And the advantages and disadvantages of each method were also discussed.In addition,the progress in energy storage performance,thermal reliability and thermal conductivity of different composite PCMs was emphatically analyzed,and it may provide theoretical basis for further research in novel composite PCMs with high properties.
