▎ 摘　　要

NOVELTY - Preparation of doped graphene carbon nanofibers involves preparing a spinning solution by mixing acrylonitrile and doped graphene material with water, polymerizing using ammonium persulfate or ammonium persulfate-ammonium persulfate composite as initiator, and dissolving the product in an organic solution, electrostatically spinning the spinning solution to obtain nanofiber felt, and subjecting the obtained nanofiber felt to thermal drafting, pre-oxidizing, carbonizing and graphitizing. USE - Preparation of doped graphene carbon nanofibers used as and/or for preparation of hydrogen storage, high capacity electrode, and high-performance composite material (all claimed). ADVANTAGE - The method enables simple, highly productive, and efficient preparation of doped graphene carbon nanofibers having high regularity, improved mechanical properties, and thermal conductivity. The nano-size of the fibers avoids generation of skin-core structure and the fiber includes graphene that accelerates the dissolution of the polymeric materials.
