▎ 摘　　要

NOVELTY - device provides a method for continuously preparing porous graphene film and porous graphene film product, the device comprises a laser head, a discharging mechanism, a material receiving mechanism and a guide rail; feeding mechanism and material receiving mechanism for commonly driving a polymer film continuously uniform speed transmission in the processing area of the polymer film along the length direction, above the processing area of two sides of the feeding mechanism and material receiving mechanism are located on the polymer film of the processing area of the laser head is located on the polymer film and is installed on said guide rail; and can adjust the focus of the laser beam, and performs linear reciprocating movement in a predetermined direction on the guide rail, by ablating the polymer film in the processing area of the polymer film to form a continuous porous graphene along the vertical direction of the said polymer film to the processing area move on the guide rail. The device of the utility model can perform continuous batch of large-area porous graphene film on a polymer film substrate, and industrial production.
