Abstract

This work describes a method to create dynamic pre-programmed surface textures by an alternating electric field on coatings that consist of a silicon oxide reinforced viscoelastic siloxane network. The finite element method is developed to predict the complex deformation figures and time-resolved experimental topographical surface analysis is used to confirm them.
