Abstract

A method for coating a substrate includes disposing a deposition composition in a container. The deposition composition includes a plurality of nanosheets and a metal material. The method also includes disposing a substrate in the container, contacting the substrate with the deposition composition, applying a voltage to the substrate, electrodepositing, on the substrate, a coating that includes a metal from metal ions and the nanosheets in response to biasing the substrate at the first potential.

Claims

1. A method for coating a substrate, the method comprising:

disposing a deposition composition in a container, the deposition composition comprising;

a plurality of nanosheets; and

a metal material to produce metal ions in the deposition composition;

disposing a substrate in the container;

contacting the substrate with the deposition composition;

applying a voltage between the substrate and a counter electrode, the substrate being a cathode, and the counter electrode being an anode;

electrodepositing, on the substrate, a coating comprising;

a metal from the metal ions; and

the nanosheets.

2. The method of claim 1, further comprising disposing a reference electrode in the container.

3. The method of claim 1, wherein the metal comprises Al, Co, Ni, Cu, Ag, Au, Cr, Fe, Pb, Pd, Pt, Rh, Ru, Sn, Ti, V, W, Zn, or a combination comprising at least one of the foregoing.

4. The method of claim 1, wherein the nanosheets comprise graphene, graphene oxide, metal oxide, metal nitride, or a combination comprising at least one of the foregoing.

The method of claim 1, wherein the substrate comprises aluminum, cobalt, copper, chromium, iron, lead, magnesium, manganese, molybdenum, nickel, niobium, tantalum, titanium, tungsten, vanadium, zirconium, silicon, zinc, a rare earth element, a metal alloy thereof, or a combination comprising at least one of the foregoing.

8. The method of claim 1, wherein the deposition composition is an aqueous fluid.

9. The method of claim 1, wherein the deposition composition is a nonaqueous fluid comprising an ionic liquid.

10. The method of claim 9, wherein a ratio of a number of moles of the metal material to a number of moles of the ionic liquid is greater than or equal to 1.

11. The method of claim 1, wherein the deposition composition further comprises an ionic liquid which comprises imidazolium, pyrazolium, pyridinium, ammonium, pyrrolidinium, sulfonium, phosphonium, morpholinium, a derivative thereof, or a combination comprising at least one of the foregoing.

12. The method of claim 1, wherein the nanosheets are present in the coating in an amount from 0.001 wt % to 10 wt %, based on the weight of the nanosheets and the metal in the coating.

13. The method of claim 1, wherein the voltage is a DC voltage.
