Abstract Multi-response shape memory polymers (SMPs) received significant attention due to their deformation with a temporary shape, and retain their original shape when exposed to an external stimulus such as temperature, light, and electricity. In this study, a novel reduced graphene oxide (RGO)/water-borne epoxy (WEP)/RGO sandwich structure composite film was fabricated and investigated. The results showed that the composite film exhibited excellent thermo-, electro- and light-responsive shape memory effect, as a potential SMP that can be used for the sensors, switching devices, deployable structures, and medical apparatus.

一种具有热响应、电响应和光响应形状记忆效应的新型还原氧化石墨烯/环氧树脂夹层结构复合膜

摘要 多响应形状记忆聚合物（SMPs）由于其变形具有临时形状，并在暴露于外部刺激（如温度、光和电）时保持其原始形状而受到广泛关注。在这项研究中，制备并研究了一种新型的还原氧化石墨烯 (RGO)/水性环氧树脂 (WEP)/RGO 夹层结构复合膜。结果表明，该复合薄膜表现出优异的热响应、电响应和光响应形状记忆效应，作为一种潜在的 SMP，可用于传感器、开关装置、可展开结构和医疗器械。
