Abstract

In the attention focused biomimetic technologies, the snail shell, whose surface is antifouling, is a mimic subject. In this paper, a metamaterial technology to obtain oil repellence and antifouling, not realized on the as fabricated material surfaces, is introduced. Silicon nano-pillars imitating the real snail were evaluated in oil repellence in water. For applying this structure to complex curved surfaces, the soft resin sheet with nano-structure was developed. The fabricated sheet was applied to a tube, and evaluated in oil water mixture flowing. Antifouling and no dirt growing are obtained in the tube inner surface. As an assumed application, the bile duct catheter was fabricated and indwelled in a pig body. After 7 days placement, the catheter inner surface is antifouling, and then the metamaterial catherter indicates the practical capabilities. The demonstrated nano-structures are attractive for a new metamaterial realization.
