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.

a metal material to produce positively charged metal-containing 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 positively charged metal-containing ions; and

the nanosheets,
wherein the nanosheets comprise graphene, graphene oxide, or a combination comprising at least one of the foregoing.
