694. WE-Heraeus-Seminar: Wetting on Soft or Microstructured Surfaces
Liquid droplets are omnipresent. This has inspired numerous studies on the wetting behavior of liquid droplets under static and dynamic conditions. Many surfaces are not flat and rigid but microstructured or soft. Soft surfaces deform as soon as a droplet is deposited. Thus, droplets are surrounded by a wetting ridge and to understand the wetting behavior of soft surfaces, the interplay between wetting and elasticity needs to be taken into account. The gel can even be replaced by a lubricant, leading to very low-friction substrates. For such lubricant infused surfaces, the surface texture is key in harnessing capillary forces that lock the lubricant in place. The seminar will bring together experts and early stage researchers interested in the understanding of the wetting of soft or microstructured surfaces. We aim to assess the current status of this interdisciplinary field, to discuss future developments and to foster the exchange of concepts and techniques. The seminar targets researchers working experimentally and/or theoretically in this exciting domain of research. The topics include but are not limited to:How to understand and tune contact angle and contact angle hysteresisHow does adhesion and contact line friction couple to the reorganisation of the contact line?What kinds of energy dissipation mechanisms determine the motion of droplets?How do soft or flexible surfaces behave under shear?How to model the coupling of the wetting dynamics and substrate dynamics?How to include (de)mixing and internal degrees of freedom of liquids on the wetting dynamics?How does softness and microstructuring influence condensation, icing and evaporation of droplets?
