1. A method of coating an article comprising:
forming a coating composition by mixing a first composition of a water-soluble polymer in a solvent with a second composition of a smectite clay in water, wherein the water-soluble polymer comprises bulky side groups attached to a backbone of the water-soluble polymer and the first composition includes 0.1%-0.5% by weight of the water-soluble polymer, wherein the second composition includes 0.15%-0.45% by weight of the smectite clay, and wherein the water-soluble polymer comprising bulky side groups is selected from the group consisting of polyvinylpyrrolidone and block co-polymers of polyvinylpyrrolidone; polyethylenimine, polyaminostyrene or co-polymers of polyaminostyrene, and polyacrylic acid or co-polymers of polyacrylic acid; and
forming a coating layer on the article by the method of:
applying the coating composition to the article; and
allowing the coating composition to dry and self-assemble to form an intercalated barrier coating on the article, wherein the intercalated barrier coating has a structure that is ordered with multiple orders.
