(Towards) bio-intelligent materials

Prof. Dr. Ralf B. Wehrspohn, Microstructure-based Materials Design, Martin Luther University Halle-Wittenberg

The wetting behavior on 2D and 3D surfaces for e.g. polymer processing or nanostructuring is still in detail unknown and difficult to measure since inner surfaces are difficult to characterize. Similarly, hierarchically structured polymer nanostructures or metamaterials with improved mechanical properties exhibit similar problem understanding their detailed behavior.

For understanding wetting behavior as inner polymer nanostructures,
3D microscopy is of utmost importance. Since about 10 years now, 3D X-Rays Microscopy with nanometer resolution is available for
university research. With our microscopic technology, we are able
to understand for the first time the wetting kinetics and the principles of hierarchically structured polymers.

At the end of the seminar, the limits in resolution are discussed and possible ways to circumvent them are presented such as expansion
microscopy.
