摘　　要：利用聚乙二醇(PEG)的熔融分散、热塑性环氧树脂(Ep)的原位聚合和硬化成型工艺,开发了具备光热响应形状记忆功能的Ep/石墨(Gr)/PEG复合材料(EpGP),考察和分析了不同PEG含量EpGP的微观形貌、表面性能、化学结构、结晶性能和力学性能,并深入探究了EpGP在热刺激和光刺激下的形态记忆响应功能和响应灵敏性。结果显示:所开发的EpGP具有可光、热双刺激的形状记忆响应功能,实现了形状记忆响应时间可控,且PEG提高了EpGP的形状记忆响应灵敏性。此外,随着PEG含量的增多,EpGP逐渐从刚性转变为柔性,且力学性能获得了调控。In this work,Epoxy/Graphite(Gr)/Polyethylene Glycol(PEG)composite(EpGP)with photothermal responsive shape memory functionality was developed utilizing the melt dispersion of PEG,in-situ polymerization of thermoplastic epoxy resin(Ep),and hardening molding process.The microstructure,surface properties,chemical structure,crystallization behavior,and mechanical properties of EpGP with different PEG contents were investigated and analyzed.The shape memory response function and response sensitivity of EpGP under thermal and photonic stimuli were also deeply explored.The results indicate that the developed EpGP exhibits excellent thermal stimulus shape memory response and possesses photothermal responsive shape memory function.This work achieves adjustable shape memory response time of EpGP under thermal and photonic stimuli through PEG,which can improve the sensitivity of the shape memory response of the developed EpGP under thermal and photonic stimuli.In addition,the mechanical properties of EpGP are regulated,and EpGP gradually transitions from rigid to flexible as the PEG content increases.In summary,due to its excellent shape memory function,controllable response time,and selectable response conditions,the developed EpGP shows promising application prospects in the field of smart materials.
