▎ 摘  要

NOVELTY - The method involves carbonizing a cloth base in a plasma stream of a plasma process. The cloth base is provided with fibers that are not fully carbon. The graphene petals are grown integrally on the carbonized cloth base using the same plasma process. The plasma process comprises a plasma-enhanced chemical vapor deposition process and the process of carbonizing a cloth base and growing graphene nano-petals (102). The cloth base is provided with one or more woven structures. The cloth base is provided with cellulose fibers and synthetic fibers. USE - Method for growing graphene nano-petals on carbon fiber. ADVANTAGE - The cost of manufacture of the nano-petals can be reduced. The use across a variety of applications can be improved. The cost-effective substrates are achieved. The carbonized cotton is used as the base for graphene nano-petal which allows for reduction in cost of the finished product and enables the use of grown graphene nano-petal products in low cost applications. DETAILED DESCRIPTION - The plasma process is selected from the group consisting of a microwave plasma-enhanced chemical vapor deposition process, a radio frequency plasma-enhanced chemical vapor deposition process, a low pressure chemical vapor deposition process and a direct current arc discharge process. The fiber based cloth is used as a base material, and is provided with one or more fibers that are not fully carbon. The fiber based cloth is introduced into a plasma process chamber. The reactant gas is introduced into the plasma process chamber with a predetermined proportion of flow rates and pressure. The plasma is enabled with a predetermined power level to carbonize the surface of the not fully carbon fibers within the plasma process chamber such that graphene petals grow on the carbonized surface of the fibers. The reactant is a mixture of methane and hydrogen gases and the hydrogen gas contributes to passivate dangling bonds at edges of the graphene petals and enables the graphene petals to retain an open structure. The reactant gas is a mixture of at least methane and argon gases. The fibers comprise synthetic fibers selected from a group consisting of polyester, Rayon, and Kevlar. An INDEPENDENT CLAIM is included for composition of matter. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope image illustrating the start of growth of graphene nano-petals on carbon fiber.
