▎ 摘  要

NOVELTY - The method involves preparing a precursor solution that contains a metal salt, a templating reagent, a buffer agent, and a first solvent, which serves as a reducing agent. A graphene oxide solution is prepared by dispersing graphene oxide in a second solvent. The graphene oxide solution is slowly added to the precursor solution at elevated temperature to permit growth of reduced graphene on rod-like metal nanowire seeds, which are formed as a result of reduction of the salt to obtain a network structure, which includes core-shell nanowires and nanowebs of graphene extending from nanowires. USE - Method for making a transparent conductive material. ADVANTAGE - The method enables realizing buffer agent functions to slowdown the reducing rate to avoid the nanowire seeds from growing into nanoparticles, where presence of halide ions of the metal halide of the buffer agent in the reactive solution can result in p-typed doping of the reduced graphene, which results in formation of the halide doped reduced grapheme. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of an optical microscope image of a transparent conductive material.
