Hydrophobic fluorinated polymer surfaces

13.12.2006
The invention at hand concerns novel hydrophobic fluorinated polymer surfaces, a method for their production and their use.<br><br>

comprised of homo- or copolymers, whereby the homo- or copolymers feature at least one fluoro-substituted aryl group. These novel fluoro-substituted aryl groups can be covalently bound to the primary polymer chain in every known way, eg via direct binding to the primary chain or via spacers.<br><br> The production of the hydrophobic surfaces, based on the present invention, is carried out simply and reproducibly, for example, by electrospinning of a corresponding polymer solution.The hydrophobic polymer surface is available in the form of particles or as particles which are connected by fibers. Typical diameters are in the range of 3 µm to 1 nm, whereby the surfaces feature contact angles of greater than or equal to 160° and water-roll angles of 0°.<br><br>

In principle, all bases are suitable for use as a substrate to be coated with the novel hydrophobic polymers, in particular those made of plastic, metal or alloys.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
