  • Publication number: 20200109483
    Abstract: A method of preparing a modified-metal surface by attaching a phosphorous-based acid to a surface of a metal: preparing a solution of the phosphorous-based acid in a protic solvent; immersing a strip of a metal work piece into the solution of the phosphorous-based acid, immersing a strip of a reference metal into the solution of the phosphorous-based acid, supplying a voltage for a duration of time, removing the metal work piece, cleaning the metal work piece, and drying the cleaned metal work piece under an inert atmosphere to obtain a modified metal work piece.

  • Publication number: 20180103643
    Abstract: Articles having functional surfaces, for example antimicrobial functional surfaces, are prepared by methods comprising anodization. Organophosphorous compounds are deposited on a surface by methods comprising anodization, followed by attaching functional compounds, functional oligomers or functional polymers. Alternatively, functional organophosphorous compounds, functional oligomers or functional polymers are deposited on a surface by methods comprising anodization.
