Abstract

The invention provides a conductive fabric and a preparation method thereof. The conductive fabric comprises, from inside to outside, an adhesive force improving layer attached to the surface layer ofa fabric substrate, a liquid metal layer, an oxygen isolation protective layer and a packaging protective layer. The preparation method comprises: applying the adhesive force improving layer to the surface layer of a fabric substrate, coating the adhesive force improving layer with the liquid metal layer, coating the liquid metal layer with the oxygen isolation protective layer, and coating the oxygen isolation protective layer with the packaging protective layer. The coating manner includes spraying, brush coating, flow coating or printing. Compared with a conductive fabric in the prior art,the conductive fabric is excellent in conductivity, fold resistance, laundering durability and tensile property. The preparation method is simple and reliable.
