摘要： 以自制聚氨酯预聚体与环氧树脂复合形成互穿聚合物网络结构，采用共混方法添加自制高导电性石墨烯，制备了电热双敏型形状记忆复合材料，研究了其性能. 结果表明，以20%(w)聚氨酯/环氧树脂为基体所制1.0%(w)石墨烯/聚氨酯/环氧树脂复合材料的分散性良好，玻璃化转变温度稍低于纯环氧树脂，拉伸强度是纯环氧树脂的93%，导电性达3.58′10-4 S/m，固定率为95.5%，回复率为97.5%，循环5次后固定率不低于95%.

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.

Key words: polyurethane, epoxy resin, graphene, thermoelectric responsive composite, shape memory
