Droplets on switchable substrates: a simulation study — •Leon Topp and Andreas Heuer — Westfälische Wilhelms-Universität, Institut für Physikalische Chemie, 48149 Münster, Germany

In this work the wetting of switchable surfaces is analyzed. These surfaces can change their hydropobicy due to an external stimulus like for example light of a defined wave length. To complement current experiments, it is desirable to study these systems also from a theoretical perpective. To evaluate the nonequilibrium effects resulting from the switching process, we performed Molecular Dynamic simulations where we modelled a droplet consisting of Lennard-Jones particles on a switchable surface. Here we present the impact of different switching frequencies on the droplet. In particular the (time-dependent) shape and the size of the resulting droplets are analyzed.
