SURFACE EVOLVER SIMULATIONS OF DROPS ON MICROPOSTS

Abstract:

An important feature in the design of superhydrophobic surfaces is their robustness against collapse from the CassieBaxter configuration to the Wenzel state. Upon such a transition a surface loses its properties of low adhesion and friction. We describe how to adapt the Surface Evolver algorithm to predict the parameters and mechanism of the collapse transition on posts of arbitrary shape. In particular, contributions to the free energy evaluated over the solidliquid surface are reduced to li...
