Abstract: Many bio-applicable materials, medical devices, and prosthetics combine both polymer and metal components to benefit from their complementary properties. This goal is normally achieved by their mechanical bonding or casting only. Here, we report an alternative easy method for the chemical grafting of a polymer on the surfaces of a metal or metal alloys using alkoxy amine salt as a coupling agent. The surface morphology of the created composites was studied by various microscopy methods, and their surface area and porosity were determined by adsorption/desorption nitrogen isotherms. The surface chemical composition was also examined by various spectroscopy techniques and electrokinetic analysis. Elements distribution on the surface was determined and successful bonding of the metal/alloys on one side with the polymer on the other one was confirmed by alkoxy amine. The composites show significantly increased hydrophilicity, reliable chemical stability of the bonding even interaction with solvent for thirty cycles, and up to 95% less bacterial adhesion for the modified samples in comparison to pristine samples, i.e. the characteristics promising for their application in the biomedical field, such as for implants, prosthetics etc. All this using universal, two-step procedures with minimal use of energy and the possibility of producing it on a mass scale.
