Biodegradable resins, having low environmental loads, are expected to have wide application in the future because they can decompose easily into carbon dioxide and water in certain environments. New functional materials could be created by modifying the biodegradable resins to include higher functions using thin-film coating or other processes. From this point of view, we formed titanium thin films on the surfaces of polyactic biodegradable resins by vacuum deposition and ion beam mixing to clarify the optimum thin film coating conditions. The thin-film layers were chemically analyzed and their conductance characteristics and adhesion strengths evaluated in relation to the biodegradable resins used to produce the thin films. We confirmed that the combined method of ion beam mixing and vacuum deposition was suitable for creating thin-film coatings on the surfaces of polyactic biodegradable resins. The thin films obtained by the combined method were found to have chemical compositions, conductivities, and adhesion strengths that would permit practical use.
