Bad Honnef, 11 – 13 April 2019
The 694. WE Heraeus-Seminar on WETTING ON SOFT OR MICROSTRUCTURED SURFACES brought together experts and early stage researchers (PhD students and postdocs) interested in the understanding of the wetting of soft or microstructured surfaces. The participants discussed in depth the latest progress and current challenges in the characterization and modelling of such surfaces. In particular, the interplay of static and dynamic wetting properties with substrate topography and softness was deliberated.
We discussed:
- How to understand contact angle hysteresis of drops on soft or microstructured surfaces.
- How to tune contact angle hysteresis.
- What determined the friction of droplets moving over soft or microstructured surfaces.
- What kind of dissipation mechanism determined the motion of droplets.
- How did contact line friction couple to the reorganisation of the contact line.
- How did the motion of drops depend on the shape of the wetting ridge, the softness of the substrate or the viscosity of a lubricating film.
- How did lubricant infused surfaces withstand shear stresses.
