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.
