The present disclosure is directed to film forming compositions comprising a first anionic or non-ionic non-crosslinking polyacrylate random copolymer and a second cationic non-crosslinking polyamide random copolymer. The present disclosure is also directed to methods of using the film forming compositions.

A process of providing an antibacterial coating to the surface of an article including the steps of applying a layer of an antibacterial precursor layer to the surface of an article to which an antibacterial coating is to be applied, wherein said antibacterial precursor layer is a precursor from which the coating is to be formed; and directing a neutral molecular hydrogen flux from a neutral molecular hydrogen flux emission source towards the surface of the article. Upon impact of neutral hydrogen molecules on molecules at or on the surface of an article, the bonds of the antibacterial precursor layer are selectively ruptured, and wherein the selectively ruptured bonds cross-link with themselves or with other chemical moieties at said surface or a combination thereof, resulting an antibacterial coating being formed on the surface of the article.
