▎ 摘　　要

NOVELTY - Preparation of graphene nonwoven fabric comprises oxidizing flake graphite to prepare graphene oxide; coating graphene oxide on surface of non-woven fabric by ultrasonic impregnation and rolling; drying to increase weight of non-woven fabric by 20-30%; putting coated nonwoven fabric in reducing solution for reduction treatment to reduce graphene oxide to graphene; and calcining coated nonwoven fabric at 1000-3000 degrees C under protective gas to carbonize nonwoven fabric and to obtain graphene nonwoven fabric. USE - Preparation of graphene nonwoven fabric. ADVANTAGE - The method can mass produce graphene nonwoven fabric under reasonable process. The graphene nonwoven fabric has high breaking performance and high electrical conductivity.
