Abstract
A method of making a transparent conductive material includes: preparing a reactive solution that contains a solvent, a metal salt which is dissolved in the solvent, and a powder of graphene oxide which is dispersed in the solvent; and simultaneously reducing metal ions of the metal salt and the graphene oxide in the reactive solution to form a plurality of core-shell nanowires, each of which includes a core of a metal reduced from the metal ions, and a shell of graphene surrounding the core.
Claims9
A method of making a transparent conductive material, comprising steps of:
- a) preparing a precursor solution that contains a metal salt, a templating reagent, a buffer agent, and a first solvent which also serves as a reducing agent;
- b) preparing a graphene oxide solution by dispersing a graphene oxide in a second solvent which is miscible with the first solvent;
- and
- c) slowly adding the graphene oxide solution to the precursor solution at an elevated temperature of no smaller than 150° C. and less than 290° C. so as to permit growth of graphene on metal nanowire seeds which are formed as a result of a reduction of the metal salt to thereby obtain a network structure which includes a plurality of core-shell nanowires interconnected to each other and a plurality of nanowebs of graphene extending from the core-shell nanowires.
