Form-stable phase change materials based on polyolefin elastomer and octadecylamine-functionalized graphene for thermal energy storage.Latent heat storage using organic phase change materials (PCMs) have the potential to alleviate the contradiction between supply and demand in energy.  However, the usage of PCMs is compromised by deficiencies including liquid leakage during liquidation and solidification, poor thermal conductivity and inferior thermal stability.  Herein, we successfully fabricated a series of novel form-stable phase change materials (FSPCMs), using the polyolefin elastomer (POE) along with the octadecylamine-functionalized graphene (C18-rGO) acted as the supporting networks and paraffin as the thermal energy storage material.  As expected, the composite FSPCMs demonstrated reliable thermal stability and high thermal energy storage capacity.  In particular, the composite FSPCMs was capable of absorbing or releasing stored thermal energy at a high rate, illustrating a great potential to be used as the effective thermal energy storage and thermal management systems.
