School on “Wetting and modeling of lubricant impregnated surfaces”, 19-20 November 2018

Textured substrates infiltrated with a lubricant form a new class of functional surfaces, known as lubricant-infused slippery surfaces. They are promising candidates for low adhesive, anti-icing and anti-fouling surfaces.

To design durable slippery surfaces, a better understanding of the interplay between the physical and chemical interactions among the surface topography, the lubricating film and the droplet under static and flow conditions is essential. After an introduction on how to chemically modify surfaces, the basic concepts to model wetting of smooth, and rough surfaces will be introduced.

This includes advancing, receding contact angles, tilting angles, and lateral adhesion forces. The consequences of a lubricating film will be discussed, including the Neumann triangle, spreading coefficient, capillary forces and elastic forces. Different mechanisms of adhesion will be introduced. Analytical and numerical methods to describe adhesion are going to be presented, including mesoscopic (Lattice Boltzmann method) and macroscopic (scaling analysis and lubrication theory) approaches.

Mid-term meeting, 21 November 2018

The mid-term meeting is an assessment of all aspect (scientific, training, management, networking, etc.) described in the Grant Agreement (Annex I- Description of the Action). Besides of that, it will give the possibility to establish a constructive dialogue between the network participants and the REA Project Officer Caroline Peters.

Heraeus seminar 2019

Wetting on soft or microstructured surfaces

Bad Honnef, 11 – 13 April 2019

 

The seminar will bring together experts and early stage researchers (PhD students and postdocs) interested in the understanding of the wetting of soft or microstructured surfaces. We aim at discussing 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 will be deliberated.

 

We aim to discuss:

  • How to understand contact angle hysteresis of drops on soft or microstructured surfaces.
  • How can we tune contact angle hysteresis?
  • What determines the friction of droplets moving over soft or microstructured surfaces?
  • What kind of dissipation mechanism determine the motion of droplets?
  • How does contact line friction couple to the reorganisation of the contact line?
  • How does 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 do lubricant infused surfaces withstand shear stresses?
