Problems solved by technology

The application of graphene materials in textiles has attracted more and more attention because of its unique two-dimensional structure and remarkable electrical and mechanical properties. It has become a new way of research on related functional textiles. Excellent electrical and mechanical properties. For example, the Chinese invention patent application with the application number 201510540291.8 discloses a graphene / cotton flexible conductive fabric and its preparation method. The surface of the cotton fabric is covered with graphene oxide by dipping-drying method, and then Graphene oxide is reduced to graphene by in-situ chemical reduction method, thus endowing cotton fabric with good electrical conductivity, but there is a problem of poor durability
The Chinese invention patent application with the application number 201610665999.0 discloses a preparation method of manganese dioxide / graphene composite carbonized cotton fabric, in which graphene oxide is soaked and coated to treat the cotton fabric, and manganese dioxide nanoparticles are deposited On the surface of graphene oxide coating to obtain good electrical conductivity, but the cotton fabric and graphene oxide in this product structure rely on intermolecular force and lack of chemical bonds, so the water resistance is poor
[0003] In addition, in the prior art, the graphene conductive finishing and dyeing process for cotton fabrics is a two-bath process, the process flow is long, and the operation is relatively complicated. In addition, in the existing process, crosslinking agents are often used to make the fabric and the finishing agent firmly bonded, which is affected by the environment. Greater impact, more complex process
