▎ 摘 要
NOVELTY - Surface modification of carbon fiber involves coating graphene solution on carbon fiber surface, drying coated carbon fiber surface, placing dried carbon fiber in plasma device, spraying plasma on the surface of carbon fiber coated with nano graphene of graphene solution in an open environment and moving the nano graphene-coated carbon fiber in plasma atmosphere at 100-1000 W for 10-900 seconds. The graphene solution is prepared using nano graphene and organic solvent or water by ultrasonic shock technique. The graphene solution is a sol solution having concentration of 0.5-10%. USE - Surface modification of carbon fiber (claimed). ADVANTAGE - The surface modification of carbon fiber is simple, economical, environmentally-friendly, and provides excellent treatment to carbon fiber with reliable quality in short period of time.
