▎ 摘　　要

NOVELTY - A graphene comprises one or more substituent containing at least one ether group and at least one amine group. USE - Graphene used in composition for manufacturing graphene fibers (all claimed) used as reinforcing material for automobiles, airplanes, leisure articles and electronic device. ADVANTAGE - The graphene has excellent dispersibility, mechanical properties, electrical properties, thermal properties and plastic strength, and suppressed defects occur during the heat treatment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a graphene composition, which comprises the graphene; and (2) manufacture of graphene fibers, which involves preparing the graphene, preparing a dispersion in which the prepared graphene is dispersed, and spinning the prepared dispersion into a coagulation bath.
