Abstract: Polyurethane (PU) prepolymer/epoxy resin (EP) composite was synthesized by interpenetrating polymer, and mixing homemade high conductivity grapheme (G), the thermoelectric responsive composite of shape memory graphene/polyurethane/epoxy resin (G-PU-EP) was prepared. The results show that the dispersibility of G-PU-EP with addition of 1.0%(w) grapheme in 20%(w) PU-EP is good, its glass-transition temperature Tg slightly lower than that of pure epoxy resin, its tensile strength 93% of pure epoxy resin and its electrical conductivity 3.58′10-4 S/m, its shape fixing rate (Rf) and shape recovery rate (Rr) are 95.5% and 97.5%, respectively. In addition, Rf remains over 95% after recycling of 5 times.
