NOVELTY - The method involves electrically spraying head over the entire drying tunnel inside in continuous operation in high temperature baking, then winding the dried film inside to form coils. The next step after coating the film is preparing a tank containing a chemical reducing agent to remove graphite oxide in the graphene film, and peeling rolling, graphene films to facilitate follow-up die-cutting and other processing. USE - Method for preparing graphene thin film. ADVANTAGE - Contains no bubbles, thus, the graphene thin film provides good thermal conductivity properties. DETAILED DESCRIPTION - The film of high temperature resistance is polyethylene terephthalate film, polyimide film or metal thin film.
