A method of preparing a modified-metal surface. The method includes preparing a solution of a phosphorous-based acid in a solvent; immersing a strip of the 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 to prepare a phosphorous acid-modified metal work piece; removing the phosphorous acid-modified metal work piece; cleaning and drying the phosphorous acid-modified metal work piece; applying a chitosan solution to the surface in order to attach chitosan/modified chitosan to the phosphorous acid based modified surface; prepare the modified-metal surface; and cleaning and drying the modified-metal surface.
A method of preparing a functional surface comprising a metal, polymer, biopolymer, or ceramic material, the method comprising:
An article comprising a work piece having a modified surface, wherein the surface comprises a polymer, biopolymer, or ceramic material, and wherein the modified surface comprises a chitosan modified with a quaternary ammonium salt.
A method of preparing a functional metal surface, the method comprising:
