| Abstract: |
| Phase change materials（PCMs） are widely used in building，thermal protection，textile and energy storage fields，and have the advantages of energy saving and environmental protection. Ethylenepropylene-diene rubber（EPDM） and silicone rubber are good materials for the encapsulation of organic PCMs such as paraffin wax and stearic acid，and the encapsulated materials shows a low leakage rate.The phase change enthalpy of composite PCMs increases with the increase of PCMs content，and the phase transition temperature changes little. Rubber materials possess excellent application prospect as the encapsulation material of PCMs. PCMs with high thermal conductivity can be produced by adding heat conductive fillers，such as aluminum oxide，expanded graphite and nitride. At present，the heat conduction modification technology of rubber is mature. |
