| Outline of Final Research Achievements |
Biomimetic engineering, inspired by living organisms, has the potential to solve a wide range of problems. In particular, liquid-infused surfaces (LIS), which mimic pitcher plants, have attracted attention for their transparency, antifouling, and self-healing properties. However, although LIS has been investigated for counter-liquid, it has not been reported from the viewpoint of tribology, and it is expected to be developed into a lubricating surface as a fundamental technology essential for high energy efficiency. In this study, we developed a LIS-type biomimetic lubricating surface. By controlling the surface morphology and wettability, the infused liquid self-heals and coats the surface, improving the lubrication performance against solid materials and achieving a low friction coefficient of 0.05.
