| Outline of Final Research Achievements |
This study had aimed at the investigation of the barnacle settlement mechanism with precisely controlled surface functional groups and microstructures for developing eco-friendly anti-fouling materials. As the results of the experiments, a surface hydroxyl group strongly inhibits the barnacle settlement, and the cross-linked poly(vinyl alcohol) coating had shown an anti-fouling property via the field experiment. Furthermore, this study revealed that surface microstructures and micro-patterned surface functional groups affect a barnacle settlement. These results suggest strategies for the development of the eco-friendly anti-fouling materials.

| Academic Significance and Societal Importance of the Research Achievements |
本申請研究では材料表面の化学組成を精密に制御してフジツボの付着実験を行い、材料表面のヒドロキシル基が強くフジツボの付着を抑制することを明らかとした。さらに一般的な高分子材料であり、側鎖にヒドロキシル基を持つポリビニルアルコールを架橋させて基板をコーティングすると、海中に浸漬しても海洋付着生物が付着せず、防汚材料として利用可能であることが示された。その他にも材料表面の官能基をマイクロスケールでパターニングすると、ヒドロキシル基の割合が多くてもフジツボが付着するなど、幾何学的なパターンも影響することが示唆されるなど、これまでに報告されていないフジツボ着生に関する多くの知見を得ることができた。
