Abstract
This chapter demonstrates that under UV illumination dynamic surface topographies can be used to modulate the surface friction. The modulation of friction is based on a reversible switch between a flat and a pre‐designed surface texture. The change in friction, both and dynamic, is employed by utilizing some materials. The dynamic friction behavior of the system is quantified by the kinetic friction coefficient (μk) and is measured by two coatings that are sliding against each other at a constant speed. A home‐built measuring system is designed to measure the dynamic surface friction. The static friction coefficient (μs) is measured by placing two coatings against each other and tilting them from the horizontal position to a deflection angle β. The chapter also demonstrates a method to bring a sample into motion by decreasing the static friction at two surfaces through UV light.
