In the manufacturing process of graphene, it is necessary to use nitrogen to protect graphene from oxidation and pollution, to improve the performance and stability of graphene.
Nitrogen displacement is used to purify methane and other gases used in production to ensure the safety of the preparation process and the quality of graphene.
To improve production efficiency, pure nitrogen, as a high-energy ion beam, can provide enough energy to generate these carbon vacancies and defects, so as to achieve efficient preparation of graphene.
