Green Superlubricity Enabled by Only One Water Droplet on Plant Oil-Infused Surfaces
The increase in energy loss due to friction and the use of large amounts of lubricants to improve it are major challenges we face from a global environmental perspective. Herein, Kengo Manabe, Researcher, Yasuo Norikane, Group Leader of Molecular Assembly Group, and Miki Nakano, Senior Researcher of Tribology Group demonstrate superlubricity with a single water droplet placed on a pitcher-plant-inspired liquid-infused surface (LIS) holding oleic acid, a component of plant oil. When a water droplet is placed on the fluid layer, the coefficient of friction (CoF) under reciprocating and rotating friction is 0.012 and 0.0098, respectively. A force in the direction opposite to the loading due to the Laplace pressure on the droplet and an autonomous positional movement of the water accompanied by the optimization of surface energy prevent direct contact between the surface and the friction material. The key technology here will serve as a step toward a sustainable green strategy for friction reduction and lubrication, which would greatly reduce energy loss and environmental degradation.
For the details, please refer to Langmuir 2021, 37, 51, 14878–14888.

Developed a surface that can hold both plant oil andwater, achieving superlubrication with a coefficient of friction of 0.01 or less
