▎ 摘　　要

NOVELTY - A composite conductive film comprises a cellulose-based material, a graphene material, and metal particles, where the cellulose material and the graphene material are overlapped with each other, and the metal particles are filled in cellulose material and the graphene material to form voids. USE - Composite conductive film use in packaging of electronic devices, dust-free workshop, and purification plant or anti-static application (claimed). ADVANTAGE - The composite conductive film has excellent electrical conductivity and can prevent the metal particle to contact with the air by addition of cellulose-based material and graphene material, thus solving the problem that the metal particles are easily oxidized when indium tin oxide is used as a conductive phase. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a composite conductive film, which involves mixing a cellulose-based material and a graphene material, adding a metal precursor and a reducing agent to obtain a mixed solution, hydrothermally reacting the mixed solution, and removing the solvent to form a film of the mixed solution to obtain the finished product.
