  • Patent number: 9534138
    Abstract: A novel Aromatic Thermosetting Copolyester (ATSP) can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene (PTFE) and other additives. Surface treatments/coatings are key to improving wear performance and durability in a wide array of applications. The problems associated with use of liquid lubricants, hard/soft coatings are well known but only modest progress has been achieved due to lack of research on new material systems. These coatings were fabricated and tested as highly effective wear resistant coatings by blending ATSP with PTFE and other tribologically beneficial additives. The main advantages of these polymeric-based coatings are their relatively low cost and simple substrate surface conditioning (i.e., no need for expensive surface preparation before coating).

  • Publication number: 20050221087
    Abstract: A composite includes substrate fibers, and an organosilica coating including a structure-directing template, on the substrate fibers. The composite may be formed by coating substrate fibers with an organosilica sol containing a structure-directing template, and curing the organosilica sol to form an organosilica coating. A nanoporous chelating fiber includes a substrate fiber and a nanoporous chelating coating, on the substrate fiber. Nanoporous chelating fibers may be formed by removing the structure-directing template from a composite to form a nanoporous chelating coating on the substrate fibers. Contaminants may be removed from a fluid by contacting nanoporous chelating fibers with a fluid containing at least one contaminant.
