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, the nanosheets comprising a basic or a cationic functional group, the basic functional group comprising a primary amino group, a secondary amino group, a tertiary amino group, or a combination thereof, and the cationic functional group comprising a quaternary ammonium group, a quaternary phosphonium group, a tertiary sulfonium group, an alkyl pyridinium group, or a combination thereof; and
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.

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.
