Nanoscale investigation of wetting and de-wetting during imbibtion and nucleation


Starting with the second funding period, the new project A09 is dedicated to nanoscale investigations of wetting and dewetting during imbibition and nucleation. It should allow a deeper understanding of surface effects on the deformation of the contact line on a nanoscopic length scale. A scanning force microscope is used to scan the contact line with a resolution of 10-30 nm. Differences between nanoscopically and macroscopically measured contact angles are analyzed. In addition to simple fluids and surfaces, mixtures and mesoporous as well as swellable surfaces are used. A nanoscale body immersed into the air/water will be used to study the local distribution of substances. This generic configuration will be compared directly with simulations.
