| Outline of Final Research Achievements |
In this program, our team tried to understand frictional and adhesion properties in the biological systems, which are closely related to the surface properties of common engineering materials, and, based upon the functional elements extracted from the biological examples, tried to propose new designs of functional materials. As results, strong adhesion mechanism of suction pad of cling-fish in water, the effects of the scales with unevenness-period grove structures of firebrat on the frictional properties, and extremely low adhesive interaction between tentacles of live Cypris larva and polyelectrolyte brush surface in sea water determined by scanning probe microscopy are mainly clarified in terms of the relationship between the functions and the surface topography/chemistry. Based upon the results, a design for shape-tunable undulated surfaces with highly variable friction was newly proposed.
