Living nature is the inspiration for many innovations and continues to serve as an invaluable resource to solve technical challenges. We find that unique surface characteristics of rice leaves and butterfly wings combine the shark skin (anisotropic flow leading to low drag) and lotus (superhydrophobic and self-cleaning) effects, producing what we call here the rice and butterfly wing effect. A systematic study has been conducted with rice leaves and butterfly wings, using a combination of actual and replica samples. In order to mimic the rice and butterfly wing effect, replica rice leaf and shark skin samples received a superhydrophobic and low adhesion nanostructured coating. The data are compared to those of uncoated samples of fish scales and shark skin. Surface morphology characterization is conducted with SEM and optical profiler imaging using software analysis. Drag is determined with pressure drop measurements from replica lined rectangular duct flow channels (using water and air in laminar and turbulent regimes). The lotus effect is shown with self-cleaning, contact angle, and adhesion force measurements. Results are discussed and conceptual models shown describing the role of surface structures related to low drag, self-cleaning, and antifouling properties.
