Abstract

The invention discloses a method and a device for continuously and rapidly preparing a graphene thin film on a copper foil. The device for continuously and rapidly preparing the graphene thin film onthe copper foil mainly comprises a laser generation system and a graphene thin film collection system. High-power pulse laser is irradiated to a graphite suspension solution, so that high-temperatureand high-pressure plasmas are instantly generated on the surface of a target material; the plasmas cannot be freely dispersed due to a restraining action of liquid at the periphery; continuous gas-state carbon is formed on the surface of the target material along self-adjustment heat conduction of a reaction region, and a feather tract range of the plasmas is continuously enlarged; the plasmas aredirectionally and locally expanded and emitted and are deposited on a substrate to form the graphene thin film. According to the technical scheme disclosed by the invention, the preparation efficiency of the graphene thin film can be improved.

Description

Technical field [0001] The invention belongs to the technical field of laser preparation of graphene films. Background technique [0002] Graphene has unique physical and chemical properties. However, tiny graphene cannot truly exert its superior properties. Therefore, research on the preparation of large-size and high-efficiency graphene is necessary. Since its inception in 2004, how to efficiently prepare graphene has attracted the attention of researchers, and theories and methods for preparing graphene have also emerged in endlessly. In addition to the traditional mechanical peeling and redox methods, there are later widely used chemical vapor deposition methods and epitaxial growth methods. At present, the laser-induced preparation of graphene technology has also become a research focus. [0003] Laser was produced in the 1960s. From its appearance to today's large-scale application, it has played a vital role in industrial production and scientific research. Especially in t...
