Wetting of soluble surfaces is present in many branches of industry. Examples can be found in the printing-, cleaning- and the foodindustry. However, the physical phenomena concerning those processes remain unclear. Since the 19th century, scientists around the world have worked on general physical models to describe wetting processes. So far, no generalized forms desribing arbitrary material matching could be deduced.

This project aims at improving the knowledge of wetting phenomena regarding solvents on soluble surfaces.

For a broad analysis of wetting phenomena on soluble surfaces, diverse polymer substrates are brought into contact with multiple solvents. Substrates are varied in respect to molar mass, tacticity and mechanical preloads. The usage of multiple solvents enables an evaluation of the effect of solubility on experimental outcomes.

Observations are made on multiple time scales. The spreading of a solvent on a polymer surface just after contact is investigated on the sub micro second scale. On the other hand, surfaces restructuring is observed after droplet spreading an evaporation.
