Novel nanostructures synthesized by polycondensation reactions of various silane precursors are presented. Our group was the first synthesizing silicone nanofilaments which are very useful for a simple conversion of surfaces, e.g. from hydrophilic into superhydrophobic surfaces. Subsequent reaction schemes lead to all kind of wetting and antiwetting properties including superoleophobic surfaces. Various application fields will be addressed. Due to appropriate adjustment of the reaction conditions it is shown that many other nanostructures can be synthesized, e.g. nano-vessels, discs, nanotubes etc.

Applications, in particular the upgrading of basic natural products into high performance products for construction materials, fabric finishing, and products for pollution removal and degradation are presented.

About the Speaker

Stefan Seeger studied chemistry at University of Heidelberg under Technical University Berlin. In 1992, he earned his PhD degree. He later studied Business administration at FernUniversität Hagen. In 1992 he established a research group for biophysical chemistry at the University of Heidelberg. After working as a postdoctoral student at the University of Lund in Sweden, he returned in 1994 to University of Heidelberg to finish his habilitation in 1997. Later that year, he was appointed as a professor for Biosensors at the University of Regensburg/Germany. In 1999, he was appointed at University of Zurich/Switzerland to a chair for physical chemistry. In 2001, he was appointed as the director of the Institute for Physical Chemistry. Currently he is a member of the board of the new Chemistry Institute at this University. Seeger invented for example the surface sensitive analysis Supercritical Angle Spectroscopy techniques, Silicone Nanofilaments, and the DAGS chemical synthesis approach. He is the founder of technology companies, e.g. Molecular Machines & Industries, the leading provider of single cell isolation technologies.
