Dual-responsive graphene hybrid structural color hydrogels as visually electrical skins

Stimuli-responsive materials have been experiencing explosive developments, which are functionally integrated with multi-signals in response to external environment variations. Here, we present a novel dual-responsive graphene hybrid structural color film as electronic skins. The film is fabricated by adding conductive reduced graphene oxide (rGO)-poly(N-isopropylacrylamide) (PNIPAM) filler into a poly(ethyleneglycol) diacrylate (PEGDA) inverse...
