  • Hydrophobic flourinated coating
    Patent number: 8871881
    Abstract: The invention at hand concerns hydrophobic polymer surfaces, in particular superhydrophobic polymer surfaces, comprising at least one homo- or copolymer, which comprises at least one side chain with at least one fluoro-substituted aryl group. Furthermore, the invention at hand concerns a method for the production of polymer surfaces of this type, their use and polymers of the general formula I: wherein n is an integer between 10 and 4,500, preferably between 20 and 2,200 and particularly preferably between 100 and 670.
    Type: Grant
    Filed: February 23, 2006
    Date of Patent: October 28, 2014
    Assignee: Philipps-Universität Marburg
    Inventors: Andreas Greiner, Seema Agarwal, Michael Bognitzki, Sven Horst
  • Parylene variants and methods of synthesis and use
    Patent number: 7994372
    Abstract: Fluorinated paracyclophane compounds represented by the formula: where least one of R1 and R2 comprises a fluorinated moiety is disclosed. These compounds can be utilized as precursor dimer compounds to produce polymeric coatings comprising copolymers of trifluorinated paraxylylene, including flexible fluorinated paraxylylene coatings.
    Type: Grant
    Filed: December 9, 2008
    Date of Patent: August 9, 2011
    Assignee: Specialty Coating Systems, Inc.
    Inventors: Rakesh Kumar, Phillip Hanefeld, Sven Horst, Markus Meise, Andreas Greiner, Michael Bognitzki
  • Production of metal nano- and mesofibers
    Patent number: 7981354
    Abstract: The invention relates to a method for producing metal oxide fibers with diameters on the micro- and nanometric scale by using electrospinning. At least one polymer is dissolved in a solvent, a metal salt is dissolved in this polymer solution, and this mixture is subsequently electrospun into fibers. Breaking down the polymer renders metal oxide fibers accessible that can be optionally reduced into the corresponding metal fibers.
