▎ 摘　　要

NOVELTY - Producing graphene based carbon fiber (S1) comprises dispersing a quantity of at least one of a graphene powder, graphene flakes, graphene oxide powder and graphene oxide flakes into a solvent solution with a surfactant, adding a small amount of at least one of a nanocellulose fiber, a polymer and a resin into the solvent, stirring the mixture to obtain an uniform viscosity solution, and forming (S20) a quantity of carbon fibers from the solution. USE - The method is useful for producing graphene based carbon fiber (claimed) which is useful for forming the parts for vehicles and machines, and in intelligent robotic human, trucks, trailers, trains, buses, trams, vans, cars, airplanes, computer cases and mother boards, as well as boats and ships in the ocean, and anti-corrosion pipes for liquids transportation including chemicals and oil-refining pipes. ADVANTAGE - The method: provides graphene based carbon fiber in economical manner; is ecofriendly; forms high quality graphene-based molding parts through the use of graphene carbon fibers and nanocomposite materials; allows for the vehicle parts manufacturing at low temperature, which does not have as much waste and pollution released to the environment; decreases the required manufacturing time to produce the designed parts; decreases the requirements of equipment for the manufacture of machine parts and articles for vehicles through additive manufacturing 3D printing; provides graphene-based parts or articles with unique and enhanced functional properties, e.g. thermo-conductivity, electric conductivity, resistance to corrosion and many other properties that will be able to be used to improve electronics, energy efficiency, lower environmental impact and increased product lifespan; and reduces the reliance on oil and petroleum to create carbon fiber.
