▎ 摘　　要

NOVELTY - Preparing amine-group-reinforced graphene fiber involves extruding oxidized graphene aqueous solution through a spinning tube where it is reacted with mixed aqueous solution of reducing agent and amine coagulating liquid maintained at 60-95 degrees C for 0.5 hours. The graphene hydrogel is reduced and self assembled to obtain amino-reinforced graphene fiber. USE - Method for preparing amine-reinforced graphene fiber (claimed). ADVANTAGE - The method enables to prepare amine-reinforced graphene fiber which has good strength, toughness, excellent thermal conductivity and electrical conductivity.
