▎ 摘  要

NOVELTY - Carbon fibers are formed by mixing graphene oxide in a solvent having a surfactant, adding polymer to solvent-graphene oxide mixture, stirring mixture to reach approximately uniform viscosity, adding a quantity of nano-cellulose fibers to the mixture, forming fibers from the mixture of graphene oxide, solvent, polymer, and nano-cellulose fibers, and heating the formed fibers in air at 200-500 degrees C. USE - Formation of carbon fibers for manufacture of carbon fiber tubes, pipes or risers, or car/airplane/computer parts, bicycles, and sports supplies. ADVANTAGE - The method provides energy savings and greener chemical process manufacturing, and lowers the cost for electrical vehicles, parts of airplanes, as well as ships in the ocean. The resulting carbon fiber piping has improved tensile strength, can endure increased temperature stress ranges, and has improved resistance to corrosion when compared to the pipes current found in use across the world.
