Abstract: Organic polymer is used usually as shell material of phase change microcapsules due to its good thermal stability and encapsulation efficiency,but the thermal conductivity of organic polymer shell is poor which affects the heat transfer performance of microcapsules.Many researchers reported that added the thermal conductive material into the shell of microcapsule or used the inorganic material with better thermal conductivity to modify the shell which can improve the thermal conductivity of microcapsules.The preparation methods of thermal conductivity enhancement microcapsules in recent years were reviewed,and its applications were also introduced.
