NOVELTY - Method for preparing a shape memory biphenyl type epoxy resin composite material involves mixing 4,4-dihydroxybiphenyl, epichlorohydrin, alkali catalyst and the first solvent to carry out a substitution reaction to obtain a biphenyl type epoxy monomer, mixing the biphenyl type epoxy monomer, curing agent, iodonium salt photoinitiator, ferrocene photosensitizer, graphene and a second solvent and thermally curing to obtain the product. USE - Method used for preparing shape memory biphenyl type epoxy resin composite material used in light stimulus intelligent response material (all claimed). ADVANTAGE - The method utilizes the activation and reorganization of the crystal phase of the biphenyl structural unit of the biphenyl epoxy monomer at high temperature, and realizes the near-infrared reprogramming behavior of composite materials and provides a new strategy for the programmable performance of biphenyl epoxy resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the shape memory biphenyl type epoxy resin composite material obtained by the above-mentioned method.
