  • Patent number: 7820563
    Abstract: Compositions and methods for treating substrates, such as fibrous materials, are disclosed. Such compositions and methods can be used to impart or maintain a level of oil repellency and/or water repellency in fibrous substrates such as paper-based materials and/or textiles. In general, such compositions can utilize a copolymer having a plurality of polycationic segments, which can be joined by various other polymeric segments such as silicones and/or hydrophilic polymeric segments. The copolymer can be formulated as a highly-branched polymer, which can have substantivity to a fibrous material to impart oil repellency and/or water repellency. In several instances, the copolymer can be formulated to be fluorine-free. Various details of such copolymers are discussed, as well as methods of utilizing and making such copolymers.

  • Patent number: 7651760
    Abstract: Disclosed is a versatile method to produce superhydrophobic surfaces by combining electrospinning and initiated chemical vapor deposition (iCVD). A wide variety of surfaces, including electrospun polyester fibers, may be coated by the inventive method. In one embodiment, poly(caprolactone) (PCL) was electrospun and then coated by iCVD with a thin layer of hydrophobic polymerized perfluoroalkyl ethyl methacrylate (PPFEMA). In certain embodiments said coated surfaces exhibit water contact angles of above 150 degrees, oleophobicities of at least Grade-8 and sliding angles of less than 12 degrees (for a water droplet of about 20 mg).
