▎ 摘　　要

NOVELTY - Electrically actuated copper-based film comprises an asymmetric structure in which one side is copper and the other side is a composite of cuprous oxide and reduced graphene oxide (rGO). USE - Electrically actuated copper-based film. ADVANTAGE - The electrically actuated copper-based film is capable of conducting heat and infrared radiation, generates response to mechanical deformation and output force, and has important application in the actuator field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the electrically actuated copper-based film, which involves: (A) using copper foil as a substrate, processing it to obtain a treated copper foil; (B) dispersing graphite oxide dispersed in water, and adjusting the pH to obtain graphite oxide dispersion; (C) coating graphite oxide dispersion liquid onto the surface of the treated copper foil to form a thin layer of graphite oxide dispersion liquid; and (D) performing redox reaction, and drying it to remove excess graphite oxide to obtain electric actuation copper-based film.
