▎ 摘　　要

This report aims to illustrate a highly effective method to obtain a kind of graphene oxide (GO)/reduced graphene oxide (RGO) paper by Ultraviolet (UV) laser direct writing method. Due to removing the oxygencontaining groups and introducing the layered micro-nano structures on one side of the GO film. The asprepared GO/RGO papers exhibit anisotropically deformation triggered by ethanol vapor and could enable the potential applications for stimuli-response actuators.
