Abstract

The invention belongs to the field of functional textile, and particularly relates to a conductive washable graphene / silver composite cotton fabric. The conductive washable graphene / silver composite cotton fabric comprises a cotton fabric matrix, a graphene single wafer layer attached to the cotton fabric matrix and a silver film attached to the graphene single wafer layer. The cotton fabric matrix is composed of cotton fabric fiber; the graphene single wafer layer is composed of graphene nano-sheets, and the graphene nano-sheets are attached to the surface of the cotton fabric fiber and alternately stretch between the cotton fabric fiber; the silver film is composed of silver particles, and the silver particles are embedded into the graphene nano-sheets, and gaps between the graphene nano-sheets are filled with the silver particles. The preparation method of the conductive washable graphene / silver composite cotton fabric comprises the steps that after plasma treatment of the cotton fabric, graphene oxide is attached and reduced, and finally magnetron sputtering is performed on a silver target material to obtain the conductive washable graphene / silver composite cotton fabric. The conductivity and washability of the composite cotton fabric are greatly improved, the quality of the cotton fabric is improved, the application field is expanded, and the commercial value is increased.
