Title:
ALL-WEATHER SELF-HEALING STRETCHABLE CONDUCTIVE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/178938
Kind Code:
A1
Abstract:
A method for preparing an all-weather self-healing stretchable conductive material, comprising: using acrylic acid and modified polyglutamic acid as base materials; adding Fe 3+ to form coordination; adjusting the volume ratio of water to glycerin; generating free radical polymerization after heating; and generating a homogeneous double-layer three-dimensional network structure, the obtained polyacrylic acid and polyglutamic acid composite hydrogel having preferable mechanical performance and the feature of quick self-healing; depositing a metal layer with 20-80 nm thickness on a single layer of in-line carbon film to prepare a composite carbon film by means of a magnetron sputtering method, and adhering the composite hydrogel to the upper and lower surfaces of the composite carbon film to form the all-weather self-healing stretchable conductive material having a sandwich structure. The method is simple and has wide raw material source, and the prepared material has preferable electrical and mechanical performances, and thus has wide application prospects in the fields of flexible stretchable devices, wearable devices, software robots, etc.
