Abstract

Provided is a method of forming a complex plating film using multi-layer graphene metal particles. The method of forming the plating film may include preparing a powder with a metal particle structure coated with multi-layer graphene, and forming a plating film by adding the powder to a plating solution through electric plating.

First claim

What is claimed is:

1 . A method of forming a complex plating film, the method comprising the steps of:
adding a multi-layer graphene-coated metal powder to a plating solution; and forming a plating film by performing electric plating in a plating solution to which the metal powder is added.

2 . The method of claim 1 , wherein the multi-layer graphene-coated metal powder is prepared through electric explosion.

3 . The method of claim 2 , wherein the preparation of the multi-layer graphene-coated metal powder includes the steps of:
coating a metal wire with a carbon-based material; and performing electric explosion of the carbon-based-material-coated metal wire in a solution or in the air, wherein the carbon-based material includes graphene or graphite.

4 . The method of claim 3 , wherein the metal wire consists of copper, nickel, aluminum, iron, gold, silver or a mixture thereof.

5 . The method of claim 3 , wherein the metal powder is prepared by coating multi-layer graphene including 1 to 20 carbon atom layers through the electric explosion.

6 . The method of claim 3 , wherein the coating of the metal wire with the carbon-based material includes the steps of:
synthesizing the graphene on a surface of the metal wire; and transferring the synthesized graphene onto the surface of the metal wire.

7 . The method of claim 3 , wherein the metal powder coated with the multi-layer graphene is prepared by performing electric explosion of the metal wire in a solution, and the solution includes at least one selected from the group consisting of isopropyl alcohol, acetone, ethanol, methanol, carbon compound solvents, glycols including carbon, glycerin, triethanolamine, methylene chloride, deionized water, distilled water, hydrogen peroxide and a metal compound solvent.

8 . The method of claim 3 , wherein the metal powder coated with the multi-layer graphene is prepared by performing electric explosion of the metal wire in a gas atmosphere including a carbon component in the air, and the gas is a hydrocarbon gas including at least one selected from the group consisting of methane, ethane, propane, butane, acetylene, cyclopentane and cyclohexane.

9 . The method of claim 1 , wherein the plating solution includes at least one selected from the group consisting of anhydrous copper sulfate, sulfuric acid and hydrochloric acid.

10 . The method of claim 9 , wherein the plating solution further includes an additive.

11 . The method of claim 10 , wherein the additive includes at least one selected from the group consisting of an accelerator, a leveling agent and a brightener.

12 . The method of claim 1 , wherein the powder is included at 1 to 10000 part per million (PPM).

13 . A complex plating film, comprising:
a plating film coated on a surface of a base material and consisting of a first metal; and a metal powder dispersed in the plating film, and including a powder of a multi-layer graphene-coated second metal.

14 . The film of claim 13 , wherein the first metal and the second metal each independently consist of copper, nickel, aluminum, iron, gold, silver or a mixture thereof.

15 . The film of claim 14 , wherein the plating film has a thickness of 2 to 50 μm.
