▎ 摘  要

NOVELTY - Preparing polyethylene glycol/graphene stabilized phase changing material involves mixing and heating polyethylene glycol and graphene to a molten state, cooling to room temperature, obtaining polyethylene/graphite melt, which is further added with a coupling agent and then and stirred to obtain polyethylene glycol/graphene stabilized phase changing material precursor A. The polyethylene glycol/graphene stabilized phase changing material precursor A is dried under vacuum conditions to obtain the polyethylene glycol/graphene stabilized phase changing material precursor B. USE - Method for preparing polyethylene glycol/graphene stabilized phase changing material (claimed). ADVANTAGE - The method enables to prepare polyethylene glycol/graphene stabilized phase changing material which avoids the leakage due to the use of PEG as the phase changing material and graphene as the adsorption material. DETAILED DESCRIPTION - Preparing polyethylene glycol/graphene stabilized phase changing material involves mixing and heating polyethylene glycol and graphene to a molten state, cooling to room temperature, obtaining polyethylene/graphite melt, which is further added with a coupling agent and then and stirred to obtain polyethylene glycol/graphene stabilized phase changing material precursor A. The polyethylene glycol/graphene stabilized phase changing material precursor A is dried under vacuum conditions to obtain the polyethylene glycol/graphene stabilized phase changing material precursor B, which is subjected to casting molding to obtain the product.
