Patent ID: 8404313

Claim:
A method of synthesizing a crystalline diamond fiber or diamond crystalline nanowire comprising the steps of: seeding a nanowire template in a nanodiamond solution, wherein the nanowire template is a non-diamond nanowire, such that the nanodiamond is seeded on the circumference of the nanowire template; placing the nanowire template in a chemical vapor deposition chamber; establishing a plasma in the chemical vapor deposition chamber consisting of a predetermined concentration of hydrogen, argon, and a hydrocarbon; and depositing diamond particles on the nanowire template by chemical vapor deposition, wherein the diamond particles form a crystalline diamond fiber or diamond crystalline nanowire, wherein the nanowire template includes a bundle of non-diamond nanowires so that a diamond shell encapsulates the bundle of non-diamond nanowires to form the crystalline diamond fiber or diamond crystalline nanowire, said bundle of non-diamond nanowires formed from a material selected from the group consisting of silicon, glass quartz, plastic, ceramic, metal, polymers, TiO, ZnO, ZnS, ZnSe, ZnTe, CdS, CdSe, CdTe, HgS, HgSe, HgTe, MgS, MgSe, MgTe, CaS, CaSe, CaTe, SrS, SrSe, SrTe, BaS, BaSe, BaTe, GaN, GaP, GaAs, GaSb, InN, InP, InAs, InSb, PbS, PbSe, PbTe, AlS, AlP, A1Sb, SiO 1 , SiO 2 , silicon carbide, silicon nitride, polyacrylonitrile (PAN), polyetherketone, polyimide, an aromatic polymer, and an aliphatic polymer.
