The concept of heat capacity factor （HCF） was used to analyze the thermal properties of the materials. The heat storage property of PCMs, containing the same content of stearic acid （23~ by mass） in the starting materials but synthesized by different technical processes, was investigated by using HCE It was found that there were vast influences of different dispersants on the heat capacity. The samples orelaared with chloroform provided the best heat storage ability in all samples tested.展开更多
