Document Type and Number:
WIPO Patent Application WO/2021/232597
Kind Code:
A1
Abstract:
Provided are a near-infrared thermal repair flexible conductive film and a preparation method therefor, belonging to the technical field of self repair materials. The preparation method of the present invention comprises the following steps: mixing graphene oxide, silver nitrate and ethylene glycol to obtain a first mixed material liquid; mixing polyvinylpyrrolidone, ferric trichloride and ethylene glycol to obtain a second mixed material liquid; mixing the first mixed material liquid and the second mixed material liquid, and subjecting the resulting reaction material liquid to a solvothermal reaction so as to obtain a silver nanowire-graphene composite material; and mixing the silver nanowire-graphene composite material, a thermoplastic polyurethane and N,N-dimethylformamide, forming a film from the obtained mixed slurry, and drying same to obtain the near-infrared thermal repair flexible conductive film. The conductive film prepared by means of the present invention has a high electrical conductivity and thermal conductivity, has a high repair efficiency under the action of near-infrared light, and can achieve multiple repairs quickly.
