Adhesion and Friction
The details of the contact between two surfaces determine their interaction strength, adhesion, and the resistance against relative motion, the friction. Friction is estimated to be responsible for ~20% of the world’s energy consumption and is consequently relevant across a wide range of technologies and scientific disciplines, as is adhesion. However, predicting both friction and adhesion remains very difficult due to the interplay of many length scales. Recent developments in both experimental, numerical, and theoretical approaches provide increasingly detailed information on the origins of friction and adhesion with unprecedented temporal and spatial resolution. This much improved understanding has also led to novel designs of interfaces and surfaces with specifically tailored properties. Notably, large progress has been made in the understanding of the role of water and humidity for adhesion and friction in biological and natural systems.
Topics covered include, but are not limited to:
- Role of surface structure and material properties in friction and adhesion
- Contact area and contact mechanics
- Local pressure and stress measurements
- Lubrication and lubrication with complex fluids
- Influence of roughness on friction and adhesion
- Instabilities during sliding friction
- Emerging tools to probe contacts at interfaces
- Examples in natural systems highlighting unique structures with consequences on adhesion and friction
- Ice friction and adhesion
- Interfacial separation: fluid flow at interfaces and the leakage of seals
