| Outline of Final Research Achievements |
In this project, we have studied fundamental aspects of photochemical reactions on polymer surfaces, particularly, proceeding when cyclo-olefine polymer (COP) surfaces were irradiated with vacuum ultra-violet (VUV) light in the presence of atmospheric oxygen. The process was successfully applied to the surface activation bonding of synthetic resin parts without using adhesive paste. Furthermore, this adhesive-less bonding based on the VUV surface-activation was extended organic-inorganic materials. By covering the inorganic surface with an alkyl self-assembled monolayer prior to VUV surface-activation, we succeeded in bonding Cu/COP and glass/COP. In addition, new VUV-surface processes has been developed. Through the VUV modification process, an ability to reduce palladium ions to its metallic nanoparticles working as catalyst for electroless plating was provided to COP surface. The VUV-reduction of graphene oxide conductable at room temperature was also explored.
