Gradient dynamics model for drops of volatile liquid on a porous substrate
Simon Hartmann, Uwe Thiele
We present a mesoscopic hydrodynamic model for a spreading drop of volatile partially wetting liquid on a solid porous layer of small thickness. Thereby, evaporation takes place un…
Drops on polymer brushes -- advances in thin-film modelling of adaptive substrates
Simon Hartmann, Jan Diekmann, Daniel Greve +1
We briefly review recent advances in the hydrodynamic modeling of the dynamics of droplets on adaptive substrates, in particular, solids that are covered by polymer brushes. Thereb…
Non-equilibrium configurations of swelling polymer brush layers induced by spreading drops of weakly volatile oil
Özlem Kap, Simon Hartmann, Harmen Hoek +4
Polymer brush layers are responsive materials that swell in contact with good solvents and their vapors. We deposit drops of an almost completely wetting volatile oil onto an oleop…
Stick-slip Dynamics in the Forced Wetting of Polymer Brushes
Daniel Greve, Simon Hartmann, Uwe Thiele
We study the static and dynamic wetting of adaptive substrates using a mesoscopic hydrodynamic model for a liquid droplet on a solid substrate covered by a polymer brush. First, we…
Sessile drop evaporation in a gap -- crossover between diffusion-limited and phase transition-limited regime
S. Hartmann, C. Diddens, M. Jalaal +1
We consider the time evolution of a sessile drop of volatile partially wetting liquid on a rigid solid substrate. Thereby, the drop evaporates under strong confinement, namely, it…
Pattern Formation in Slot-Die Coating
Maren Kasischke, Simon Hartmann, Kevin Niermann +3
We experimentally study the occurrence of pattern formation during the slot-die coating of low-viscosity nearly Newtonian liquids onto Polyethylenterephthalat (PET)-substrates. In…
Gradient dynamics model for drops spreading on polymer brushes
Uwe Thiele, Simon Hartmann
When a liquid drop spreads on an adaptive substrate the latter changes its properties what may result in an intricate coupled dynamics of drop and substrate. Here we present a gene…
