▎ 摘　　要

NOVELTY - The method involves using laser to induce partial graphitization on the surface of the flexible porous fiber material (101). The surface graphitized flexible porous fiber material is compacted at a low density using a roller press to obtain a graphene film (201). The graphene conductive film is compounded on the surface of the textile to form a composite of textile-graphene conductive film. The copper electrode flexible circuit board is attached with the silver adhesive electrode layer to the composite of the textile-graphene conductive thin film. The textile fabric is arranged on the surface of the structure of the textile-graphene conductive film-silver adhesive electrode layer-copper electrode circuit board, so that the structure of the conductive film-silver adhesive electrode layer-copper electrode circuit board-textile is formed. The hot melt adhesive is ethylene-vinyl acetate, thermoplastic polyurethane, poly-ether-sulfone or protactinium and thermoplastic polyurethane. USE - Method for preparing graphene electric heating film based on flexible porous fiber material. ADVANTAGE - The flexibility of the heating film is good. The electro-thermal film is combined with the textile substrate, and has the characteristics of ultra-soft characteristics and no abnormal sound.
