▎ 摘　　要

NOVELTY - Preparation of graphene profile, involves (i) dissolving graphene mixture grown on surface of nickel substrate obtained by chemical vapor deposition method in organic solvent to obtain liquid raw material, (ii) adding liquid raw material to hydrazine hydrate at 78-82 degrees C to obtain a product, (iii) distilling product to obtain polymer-coordinated graphene, growing on surface of nickel substrate, extracting to separate polymer-coordinated graphene from metallic nickel, and (iv) performing distillation onto to extraction of polymer-coordinated graphene to obtain graphene profiles. USE - Preparation of graphene profile (claimed). ADVANTAGE - The method promotes the physical form of graphene nano-products to linear or lattice-structured organic intermediates, and extends the application space for the application of graphene products.
