20120024789 | Surface Modification of Polyamide Reverse Osmosis Membranes - The present invention relates to surface modification of reverse osmosis membranes to introduce antifouling properties without compromising the separation properties of the original membranes. This approach utilizes: providing a coated membrane surface having enhanced hydrophilic characteristics that prevents the biofoulants from settling; have a surface that consists of hydrophilic brushes that unsettle any biofoulants that get through; and having antimicrobial ions present in the membrane coatings and able to remove or minimize any remaining biofoulants without leaching into the permeate. These coatings are made using dendritic polymers such as hyperbranched polymers or dendrimers. | 02-02-2012 |
20110054137 | NETWORKS CONTAINING PERFLUOROCARBON ORGANOSILICON HYPERBRANCHED POLYMERS - The present invention relates to hyperbranched copolymer networks containing hyperbranched copolymers that have perfluorocarbon and organosilicon entities that have high hydrophobicity, or high oleophobicity, or high thermal stability, or good adhesion to substrates, or any combinations thereof. This invention provides a further desirable combination of properties that include solubility before crosslinking, chemical resistance, and easy processibility. The copolymers may be crosslinked with a variety of crosslinking agents to give either rigid or elastomeric networks. | 03-03-2011 |
20100272810 | Delivery System for Binding and Release of Growth Factors - The present invention provides a polymer delivery system for the in vivo binding and release of growth factors, preferably orthobiologic GF, comprising a hyperbranched polymer having physiologically-acceptable anionic phosphorous groups. The hyperbranched polymer is preferred to be a polyurea with phosphonate anions. This polymer can be cross-linked to form a network and provide a coating for implanted devices. | 10-28-2010 |
20100104918 | IMPROVED FUEL CELL PROTON EXCHANGE MEMBRANES - This invention concerns an improved PEM for fuel cell applications such that the membrane is more robust. Specifically, this invention provides PEM in MEA systems that have nano-particles carrying proton conducting groups, and improved dimensional stability relative to conductivity. This invention provides a composition of matter for a high proton conductance, solid polymer electrolyte membrane, said membrane comprising: A) a nano-additive carrying proton conducting groups having a size from about 1 nm to about 1,000 run; B) a carrier polymer for the nano-additive of Part A; and C) a proton exchange membrane (PEM) or membrane electrode assembly (MEA) formed by mixing the components of Part A and Part B above. These proton conducting groups are contributed by POSS-based nano-additives or cyclic phosphazene-based nano-additives or small molecules carrying sulfonic acid groups in fuel cells or batteries. | 04-29-2010 |
20100019169 | REMOTE LASER INTERROGATION OF THREAT CLOUDS AND SURFACES - This invention concerns the remote detection of threat clouds and evaluation of their components. Also included is the remote detection and evaluation of contamination on surfaces or in air streams. To enable this detection, fluorophores that are attached to POSS are used with two-photon LIF imaging that provides enhanced background-free imaging even in the presence of scattering particles such as dust, sand and water droplets. | 01-28-2010 |
