A05 aims at the understanding of the relationship between wetting and transport on swellable polymer surfaces. The work with static polymer systems is extended to dynamically switchable polymers. The dynamic wetting and transport processes are analyzed under quasi-stationary conditions. In a "rotating capillary", the capillary-forced, progressive wetting can be stopped by a centrifugal force in order to study the pure swelling behavior or the progression of the precursor film. This enables the separation of macroscopic flow effects from wetting effects.

A05旨在理解可膨胀聚合物表面的润湿和输运之间的关系。静态聚合物系统的工作扩展到动态可切换聚合物。分析了准平稳条件下的动态润湿和输运过程。在“旋转毛细管”中，毛细管强迫的渐进润湿可以被离心力阻止，以便研究纯粹的膨胀行为或前驱体膜的进展。这使得宏观流动效应与润湿效应得以分离。
