▎ 摘　　要

NOVELTY - Preparation of conductive film graphene comprises (i) placing coating solution into lower hopper, setting glass plate on bracket along horizontal direction flatly spreading, (ii) controlling blanking hopper to move along blanking groove, rotating blanking screw to rotate, continuously and uniformly injecting coating solution in blanking hoop to blanking slot, (iii) controlling discharging groove to move relative to bracket, discharging coating solution, coating on glass plate, (iv) moving glass plate to whole glass plate relative to the bracket to be coated with coating solution; (v) taking glass plate coated from the bracket, carrying out subsequent process, and finishing preparation of graphene conductive membrane. USE - Preparation method of graphene conductive film. ADVANTAGE - The method avoid the problem of uneven coating caused by poor fluidity of the coating solution, improving the coating effect, and ensuring the quality of the prepared graphene conductive film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a preparation method of graphene conductive film. 3Blanking hopper 13Baffle 31Polishing disc 32Belt pulleys 33Transmission belt
