NOVELTY - Preparing multilayer graphene fiber paper involves ultrasonically dispersing and pre-dispersing pre-treated graphene oxide powder in deionized water to form a precursor liquid, preparing layer of graphene oxide on the non-woven fabric by vacuum suction filtration, and finally forming a non-woven fabric with a graphene oxide film, depositing zinc oxide (ZnO) thin film on a nonwoven fabric with a graphene oxide film by RF magnetron sputtering, and simultaneously reducing graphene oxide to graphene during deposition to obtain a film with a ZnO thin film and a graphene film. A woven fabric having a graphene film attached to the nonwoven fabric and a ZnO thin film adhered to the graphene film. The non-woven fabric is cleaned with a ZnO thin film and a graphene film through an acetic acid solution, removed e ZnO thin film, and a non-woven fabric with a layer of graphene film is obtained and multilayer graphene fiber paper is formed. USE - Method for preparing multilayer graphene fiber paper. ADVANTAGE - The method enables to prepare multilayer graphene fiber paper, which increase toughness and foldability of the film, and is convenient for carrying and application.
