Antioxidant graphite was prepared from Al(H 2 PO 4 ) 3 solution by solution impregnation method. The as-prepared antioxidant graphite was further compounded with phase change materials for heat storage depending upon the form-stable technique. SEM with EDS analyses were used to characterize both the morphology and microstructure of the impregnated graphite while DSC were used to measure thermal properties of the composite. The results showed that the best impregnation mass ratio of Al(H 2 PO 4 ) 3 to graphite should be 2:1∼3:1. In this case, the obtained composite heat storage material can realize certain oxidation resistance and obtain good heat storage performance after thermal cycling.
