Abstract

original image

Modified graphene can self-gel at the liquid–solid interface in a face-to-face manner to form an oriented conductive hydrogel film. This unusual gelation behavior enables a new generation of electroconductive hydrogels combining exceptional mechanical strength, high electrical conductivity, mechanical flexibility, and anisotropic responsive properties. Scale bar: 1 μm.
