    Abstract: A method for manufacturing a graphene plastic film includes the steps of providing plastic particles and graphene powder, mixing the plastic particles with the graphene powder in a weight ratio not greater than 2% to form a mixed material, heating the mixed material to form a melted material (100), pressing the melted material (100) to form a graphene plastic sheet (210), and radially stretching a periphery of the graphene plastic sheet (210) to expand and thin the graphene plastic sheet (210) to form a graphene plastic film (220). By adding graphene to the mixed material, physical properties of the graphene plastic film (220) can be enhanced. In comparison with the current technology, it is easier to be manufactured and wider to be applied.
