▎ 摘　　要

NOVELTY - A double-stimulus source-responsive porous graphene actuator comprises a flexible polymer film. A graphene film is provided on one side surface of the polymer film. The graphene film is a multi-layer structure. A micro-air hole is formed between the adjacent graphene layers. When illumination or voltage is stimulated, the actuator is bent and deformed. USE - Double-stimulus source-responsive porous graphene actuator used in worm crawling robot, flexible mechanical claw, bionic hand and kicking robot (claimed). ADVANTAGE - The double-stimulus source-responsive porous graphene actuator has excellent bending deformation, mechanical performance and use effect, and is environmentally-friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation method of double-stimulus source-responsive porous graphene actuator, which involves (1) uniformly depositing graphene oxide dispersion liquid on a glass substrate, and drying to form a graphene oxide paper of multi-layer structure, (2), immersing the graphene oxide paper in hydroiodic solution under dark conditions to obtain reduced graphene oxide paper, (3) washing the reduced graphene oxide paper with deionized water and ethanol solution, and drying, (4) preparing a single-sided belt adhesive polymer film, and bonding the dried reduced graphene paper to the polymer film to form a double-layer film structure, and (5) applying a direct current (DC) voltage to the double-layer film structure to form a micro-porous structure between the multilayer graphemes; and (2) use of double-stimulus source-responsive porous graphene actuator.
