Abstract

The invention relates to an electrochemical driving type color-changing and deformation double-response actuator and a preparation method thereof. The actuator takes polyvinylidene fluoride gel electrolyte containing lithium salt as a middle layer, and color-changing and deformation double-network structure films are arranged on the two sides of the middle layer; wherein the color-changing deformation double-network structure thin film is a single-wall carbon nanotube conducting layer loaded with a vanadium pentoxide nanowire. The compound has good optical performance and actuating performance, and is high in conversion rate and good in flexibility, so that the compound has wide application prospects in the fields of sensing, anti-counterfeiting, fabric display, camouflage and even military industry.
