Research Progress of Mechanical Properties Evaluation Methods of Microencapsulated Phase Change Materials

Microencapsulated phase change materials（MicroPCMs） have been widely used in many fields,such as aerospace aircraft,new fighter,radar system,energy efficient building, waste heat recovery,agricultural greenhouse,hot and cold circulating fluid,and thermostat clothing,etc.From the point of view of meeting the requirements of practical application, MicroPCMs＇ wall should have good mechanical properties.However,different applications have different requirements on the mechanical properties of MicroPCMs＇ wall.Research progress at home and abroad on the evaluation methods of MicroPCMs＇ mechanical properties were reviewed. It was pointed out that mechanical property evaluation methods with wider range of applications should be developed on the basis of comprehensive analysis of MicroPCMs particles＇ stress state in several typical applications.
