Structure formation in ultrathin films of soft matter on chemically (in)homogeneous reactive and non-reactive substrates — •Uwe Thiele1, Michael Bestehorn2, Karin John1, and Markus Bär1 — 1Max-Planck-Institut für Physik komplexer Systeme, Nöthnitzer Str.38, 01187 Dresden — 2Lehrstuhl für Statistische Physik und Nichtlineare Dynamik, BTU-Cottbus, Erich-Weinert-Strasse 1, 03046 Cottbus
A continuos model for an ultrathin partially wetting liquid film on a solid substrate is employed to study the structure formation of such a film on a heterogeneous substrate. We describe (1) film profiles on periodically patterned substrates, (2) sliding drops on substrates with an externally imposed wettability gradient and (3) moving droplets on a reactive substrate.
