▎ 摘　　要

NOVELTY - The method involves continuously and uniformly conveying a polymer film (3) along length in the processing area of the polymer film. The pre-adjusted focal length laser light is linearly reciprocated in a predetermined direction. The polymer film is ablated in the processing area of the polymer film to form continuous porous graphene. The predetermined direction is the moving direction of laser and width direction of polymer film. USE - Method for continuously preparing porous graphene film for manufacturing of electronic device, wearable device, micro-nano-sensor, and energy battery. ADVANTAGE - The continuous large-area production of porous graphene films is achieved by using low-power laser. The equipment requirements are reduced. The production efficiency and film quality of porous graphene film are improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for continuously preparing porous graphene film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for continuously preparing porous graphene film.
