AI Technical Summary
The existing graphene thermal conductive film preparation process suffers from problems such as high energy consumption, low efficiency, and inability to achieve continuous production due to intermittent graphitization.
The apparatus for preparing graphene roll film using continuous graphitization utilizes the conductivity and flexibility of reduced graphene oxide film. Graphitization is achieved through an electrically heated roller zone, combined with a liquid-sealed feed and discharge zone, forming an immersion liquid-sealed structure to realize continuous production of graphene film.
This significantly reduces energy consumption, shortens production time, and reduces material costs, enabling efficient and continuous production of graphene roll film.
