Abstract

The invention relates to a graphene / cotton cloth flexible conducting fabric and a preparing method of the graphene / cotton cloth flexible conducting fabric. The graphene / cotton cloth flexible conducting fabric is prepared through the following steps of adsorbing oxidized graphene through cotton fabrics, and then performing in-situ chemical reduction. An impregnation-drying method is used for covering the oxidized graphene on the surface of the cotton fabric fiber; then, an in-situ chemical reduction method is used for reducing the oxidized graphene into graphene, so that the cotton fabric has good conducting performance. The applied method has the advantages that the use of surfactants, auxiliary agents and toxic substances is avoided; the preparing method belongs to a safe, simple, convenient, green, energy-saving and environment-friendly preparing method.

Description

technical field [0001] The invention belongs to the field of flexible conductive fabrics and preparation thereof, in particular to a graphene / cotton flexible conductive fabric and a preparation method thereof. Background technique [0002] The development of conductive fibers has a history of nearly 50 years, and its development process roughly includes four stages: metal fibers, carbon fibers and composite conductive fibers containing carbon black polymers, conductive fibers containing metal salts, conductive polymers fiber. Conductive fabrics are made by weaving conductive fibers mixed with clothing fibers or carrying conductive materials, such as metals, carbon materials, and conductive polymers, on clothing fabrics. Therefore, conductive fabrics can generally be divided into metal conductive fabrics, metal-plated conductive fabrics, conductive polymer composite conductive fabrics, and carbon material composite conductive fabrics. Conductive fabrics have been widely use...
