Microencapsulated phase change materials (MicroPCM) were successfully fabricated by encapsulation of sodium thiosulfate pentahydrate (SoTP) as core with silica shell using sol-gel method. The chemical structure, phase analysis, surface morphology, thermal properties and thermal stability of the Micr...
