The heat release characteristics of microcapsule phase change materials have attracted wide attention from scholars at home and abroad.The two preparing methods of microcapsule phase change material (MCPCM) were introduced,particularly the in-situ polymerization and interfacial polymerization methods.It summed up the ways of improving the microcapsules' density,poor stability,low thermal conductivity,and reducing free formaldehyde.Microcapsules were finished on the fabric with thermal storage and temperature regulation functions by padding,coating and melt spinning ways.Finally,the research direction was prospected in terms of MCPCM and pointed out that MCPCM with environmental protection,high density,high thermal stability and good thermal conductivity had a broad application prospect.
