▎ 摘  要

(CN213356969-U) NOVELTY - In order to reduce the device cost of preparing graphene by electric flash evaporation method, the utility model claims a high temperature reaction tube for preparing graphene by electrifying carbon powder, which is a double-layer tube composed of a polymer inner tube and a metal outer tube tightly combined. The double-layer tube can be repeatedly used for thousands of times, effectively reducing the cost of preparing graphene by electric flash evaporation method, providing a new process technology for large-scale production of graphene.
