The Influence of Radio Frequency Magnetron Sputtering on Biodegradable Polymers Surface Properties

Abstract:

The paper investigated the modifying possibility of the biodegradable polymer materials surface (polylactic acid and polycaprolactone) in radio frequency discharge plasma, initiating hydroxyapatite solid target sputtering. It was demonstrated that discharge plasma treatment adjusts the surface properties of biodegradable polymers – surface free energy and the wetting angle. The disadvantage of biodegradable polymers, limiting their use in reconstructive medicine, is their hydrophobicity. The surface of biodegradable polymers becomes hydrophilic after modification.
