摘要: We reported here a facile, green, and simple method to fabricate moisture-responsive graphene actuators by moderate flash reduction of oxides (GO) films. Due the limited light transparency thermal relaxation, oxygen containing groups (OCGs) on GO sheets could be selectively removed from radiation side, forming photoreduction gradient along lateral direction film. In this manner, we obtained reduced (RGO)/GO bilayer The RGO/GO film can bend RGO side when exposed moisture because layers show different absorption capabilities water molecules. Taking advantage controllable deformation, fabricated including crawler claw robots.
