| Outline of Final Research Achievements |
We have developed the technology of surface modification and thin film formation for creating physically and chemically functional surfaces due to structure control and functionalization of organic material surfaces using low-pressure plasma with controlled ions, radicals and light. In this study, we have investigated the surface interaction between plasma and PEEK (polyether ether ketone), which is promising for biomaterial applications. Due to irradiation of argon-oxygen mixed plasma generated with non-equilibrium plasma control technology, the formation of a fine structure on the PEEK surfaces have been confirm. Moreover, it was confirmed that oxygen-based functional groups were added to the surface. From the results of the change in structure and the chemical structure of the surface, a wide range of applications from applications to biomaterials to processing for joining dissimilar materials are expected.
