Abstract: The invention relates to the use of an electrolytic bath for electroplating zinc-particles metal composite coatings of metals with antibacterial ability, which inhibits bacteria growth such as Escherichia coli and Staphylococcus aureus, at least by 87% over its surface. The method of formulating an electrolytic bath that allows the production of antibacterial coatings involves: a) adding metal particles with antibacterial ability suspended in a cationic surfactant to an electrolytic bath containing boric acid, chlorides, polyethylene glycol, benzylideneacetone, sodium benzoate, triethanolamine and dissolved Zn2+salts; b) electroplating the metal composite coating of zinc-antibacterial metal particles by applying direct current density. The occlusion of metal nanoparticles with antibacterial ability in the coating matrix provides a coating with antibacterial characteristics.

Abstract: The present invention proposes the use of an electrolytic bath to electroplate metal composites of nickel-phospohrous-metal nano-particles having antibacterial ability, which inhibits bacteria growing, such as Escherichia coli and Staphylococcus aureus, at least on 99% of its surface. The method of formulating an electrolytic bath allowing to obtain antibacterial coatings includes the following steps: a) adding p3+ ions to an electrolytic bath containing dissolved Ni salts, b) adding to the electrolytic bath metal nano-particles having antibacterial ability suspended in a cationic surfactant, c) electroplating the antibacterial composite metal of Ni—P-metal by applying a direct current density. The occlusion of metal nano-particles having antibacterial ability in the coating matrix provides it with antibacterial features.

Abstract: A surface treatment process which enables a substrate (polymer) to be given specific physical properties, especially surface nanoporosity, for example with a view to electroless metallizing it, and which completely replaces surface treatment by sulfo-chromic pickling. The surface treatment includes a hybrid UV/corona treatment of the substrate surface followed by non-electrolytic metallization. A device for implementing these processes is also disclosed.
