Outline of Final Research Achievements

This study established a 3D modeling method for Inter Crossliking Network (ICN) gel using digital fabrication tools and evaluated the surface properties of the molded structures. Based on the obtained knowledge, ICN gel structures that can be applied to real tasks such as pumps and actuators were investigated, prototypes were fabricated, and the advantages and challenges of using ICN gel were extracted through evaluation methods for each application. In addition to the performance of the gel itself, we proposed a surface modification method using the discharge mechanism of the fibrous gel, and confirmed that a self-cleaning surface can be created by the hydrogel. Combined with the proposed method, it is expected to be implemented in soft robots that can perform tasks while keeping the surface clean.

Academic Significance and Societal Importance of the Research Achievements

固体表面の濡れ性の制御は、防汚表面やセルフクリーニング表面の構築の上で非常に重要である。例えばエアコンや調理場のファン、今後活躍しうるやわらかいロボットといった製品の固体表面は、その設置環境で想定される汚れを防ぐ必要がある。これまで、有機フッ化化合物で表面を覆うことで汚れにくい表面は開発されてきたが、製造コストと環境負荷が大きかった。本提案では、表面に特殊なコーティングをせずに汚れを落としやすいハイドロゲルと微細加工技術を組み合わせることで、簡易的にセルフクリーニング表面を形成できる。本技術は、セルフクリーニング表面構築への応用の上で極めて有用であり、本分野発展に資する。
