NOVELTY - The method involves using single-layer or at least one graphene sheet to weave graphene fiber filament. The fiber bundle composed of multiple graphene fiber filaments is spun into a fiber line, and woven into a graphene grid cloth. The fiber filament in the fiber bundle is changed into an inclined state through the rotating spinning process can enhance the heat-conductivity of the. The graphene fiber line is made to form a W-M curve by weaving. The number of graphene sheets arranged along the vertical direction of the heat conduction film are increased. The heat conduction capacity is improved in the vertical direction. The high heat-conductivity metal is deposited in the fiber gap of the graphene fiber cloth by chemical plating or electroplating. The method further involves soaking the fiber cloth in the liquid made of heat-conducting material e.g. heat-conducting silica gel and rubber aluminum oxide. USE - Method for preparing high heat-conducting graphene film. ADVANTAGE - The method enables adjusting the size of the gap left when graphene the fiber cloth to adjust the vertical heat conducting coefficient of the direction of the heat conducting film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the graphene fiber cloth enhanced heat conducting principle in vertical direction.
