Abstract
Disclosed is a preparation method of an all-weather self-healing stretchable conductive material, which uses acrylic acid and modified polyglutamic acid as a substrate, adds Feto form coordination, adjusts the volume ratio of water and glycerin, and heats to generate radical polymerization, so as to obtain a uniform double-layer three-dimensional network structure. The obtained polyacrylic acid and polyglutamic acid composite hydrogel has good mechanical properties and characteristics of rapid self-healing. A composite carbon film is prepared by depositing a metal layer of 20 nm to 80 nm thick on a single-layer aligned carbon film by magnetron sputtering, and then the composite hydrogel is adhered to each of the upper and lower sides of the composite carbon film respectively to form an all-weather self-healing stretchable conductive material of a sandwich structure. The preparation method of the invention is simple, the source of raw materials is plenty, and the obtained materials have good electrical and mechanical properties and have broad application prospects in the fields of flexible stretchable devices, wearable devices, and soft-bodied robots and the like.
