Abstract:
1. A method for fabricating coiled nano carbon material, comprising: providing a substrate, and cleaning the surface of said substrate; immersing the substrate in a noble metal catalyst solution which contains a noble metal catalyst, thereby forming a noble metal catalyst crystallite nucleus layer on the surface of the substrate, wherein the noble metal catalyst is selected from the group consisting of a first catalyst group, a second catalyst group, and combinations thereof; wherein the first catalyst group is selected from an organic chelate chelated with platinum, palladium, rhodium, chrome, ruthenium, osmium, or iridium, and mixtures thereof; wherein the second catalyst group is selected from a solution of chloride, sulfate, acetate, and mixtures thereof comprising one selected from platinum, palladium, rhodium, chrome, ruthenium, osmium, iridium, and mixtures thereof; drying the substrate having the noble metal catalyst crystalline nucleus layer; disposing the substrate having the noble metal catalyst crystallite nucleus layer formed thereon in a vacuum chamber; performing a thermal chemical deposition (TCVD) process introducing an inert gas and a carbon source gas into the chamber with a initial vacuum, heating the chamber to a predetermined growth temperature, and growing a composited nano carbon material layer on the substrate with a predetermined growing time; wherein the organic chelate is “A” (copolymer of styrene monomer and N-isopropylacrylamide monomer (Poly(Styrenea-Co-NIPAAmb)), “B” (copolymer of styrene monomer and polyester oligomer), “C” (copolymer of styrene monomer and methyl methacrylate (PS-co-PMMA[poly(styrene-co-methyl methacrylate)])), “D” (ethylene vinyl acetate copolymer), “E” (copolymer of polyvinyl acetate and chitosan (poly(vinyl acetate) chitosan(CS)-graft-poly(vinyl acetate)), or combinations thereof; wherein the composited nano carbon material layer comprises the coiled nano carbon material, and the coiled nano carbon material is a mixture containing a coiled nano carbon tube and a coiled nano carbon fiber; wherein the amorphous matrix of said coiled nano carbon fiber has crystallized carbon nanoparticles; where the average measured quantity of the coiled nano carbon material in the composited nano carbon material layer is at least 30%.
