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.
