| Outline of Final Research Achievements |
This study demonstrated photocatalytic-assisted transfer printing. The photocatalytic-assisted transfer printing is a process, in which a thin film is transfer-printed to be a micro-pattern by using a specified glass or PDMS stamp with TiO2 layer. The photocatalytic effect generated by UV-irradiated TiO2 decomposed molecules of releasing layer (polystyrene or AHAPS self-assembled monolayer), so that a Au thin film was easily released from the stamp and was successfully transfer-printed to a PET substrate with low releasing force. Especially, it was found self-assembled monolayer of releasing layer was preferable for this proposed process because of easily decomposed molecules. Graphene oxide (GO) nanoparticles were also micro-structured by the transfer printing and the related printing technologies. A micro-bridge of laminated thin film of Au and GO nanoparticles had better mechanical properties than that of Au thin film.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では光触媒をトランスファプリント（TP）の離型処理に応用している．光触媒効果は一部の高分子加工などを除き，親水化や防汚化が主目的で，離型処理への適用例はない． 提案手法は成膜性と離型性を両立させ，従来の表面改質とは異なる原理で，加工学・表面工学分野で新規性・独創性の高い知見が得られた．また，酸化グラフェン（GO）ナノ粒子をAu薄膜の強化材へ応用し，TPによる微細構造化した．グラフェンは有用な機械材料だが構造化が困難で，GOナノ粒子は機械材料としての応用例が少ない．本研究によりGOナノ粒子の新たな用途を実証でき，ナノ・マイクロ領域の加工学・材料工学で新規性の高い知見が得られた．
