▎ 摘  要

NOVELTY - Preparing carbon nanofiber/graphene nano-sheet comprises (i) dispersing the 0.2-2 wt.% graphene nanosheets uniformly in the mixed solvent with the 2-20 wt.% core layer polymer dissolved to make the core layer precursor A, the core layer polymer comprising at least one of polyacrylate and/or polyolefin alcohol, the mixed solvent comprises at least one of acetone, ethanol, deionized water, and/or N,N-dimethylformamide, the shell layer precursor B is prepared by uniformly mixing the 2-50 wt.% shell layer polymer and 1-20 wt.% soft template organic matter in the shell layer solvent, the shell polymer comprises at least one of polyacrylonitrile, polymethacrylate, phenolic resin, furan resin, coal tar asphalt and/or petroleum asphalt, the soft template organic matter comprises at least one of polyvinylpyrrolidone, polydopamine, melamine, and/or aminopyridine and the shell layer solvent comprises acetone, N,N-dimethylformamide, tetrahydrofuran or ethanol. USE - The method is useful for preparing carbon nano-fiber/graphene nano-sheet. ADVANTAGE - The method: is simple, easy to scale production, environment-friendly and economical; saves energy; and prepares carbon nano-fiber/graphene nano-sheet with high specific surface area, rich multi-stage hole structure and excellent adsorption performance.
