▎ 摘  要

NOVELTY - The manufacturing method involves preparing a reactive solution that contains a first solvent, a metal salt, and a powder of graphene oxide. The metal salt is dissolved in the first solvent, and the powder of graphene oxide is dispersed in the first solvent. The metal ions of the metal salt and the graphene oxide in the reactive solution are simultaneously reduced to form core-shell nanowires (20). The nanowire includes a core (201) of a metal reduced from the metal ions, and a shell (202) of graphene surrounding the core. USE - Manufacturing method of transparent conductive material (claimed) used for electrodes of optoelectronic devices. ADVANTAGE - The buffer agent functions to slow down the reducing rate to avoid the nanowire seeds from growing into nanoparticles. The presence of halide ions of the metal halide of the buffer agent in the reactive solution results in p-typed doping of the reduced graphene, which results in formation of the halide doped reduced graphene to generate positive charges in the reduced graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a transparent conductive material. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of a transparent conductive material. Core-shell nanowires (20) Conductive coating layer (22) Nanowebs (23) Core (201) Shell (202)
