NOVELTY - Filter membrane prepared by co-growing graphene by copper plating on a copper mesh, comprises copper mesh, 1-10 %mass modified graphene solution, 85-95 %mass electroless copper plating solution, and 0.1-5 %mass acid-base regulator. USE - The filter membrane is used in a filter for purification equipment such as air purifier, humidifier and water purifier. ADVANTAGE - The filter membrane has excellent antibacterial and filtering performance, effectively blocks toxic and harmful particles, and protects human health. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the filter membrane, comprising (a) preparing a modified graphene solution, (b) preparing an electroless copper electroplating solution, adding it to the modified graphene solution obtained in step (a), and stirring and mixing evenly, and (c) using pure copper as the positive electrode and copper mesh as the negative electrode in the mixed solution obtained in step (b), when the power is turned on, the positive electrode forms copper ions, which, together with the copper ions in the solution and the modified graphene, are released to the negative electrode copper mesh and reduced to form a graphene composite copper mesh filter membrane, and according to the reaction speed, continuously adding the modified graphene solution and the electroless copper plating solution during the reaction.
