  • Zwitterionic/amphiphilic pentablock copolymers and coatings therefrom
    Patent number: 8629210
    Abstract: A zwitterionic/amphiphilic pentablock copolymer was prepared using atom transfer radical polymerization (ATRP). The pentablock copolymer is prepared for the atom transfer radical polymerization of a PDMS-PEO-Br macroinitiator and SBMA. The pentablock copolymer is incorporated into a polyurethane coating composition which is useful for antifouling and/or fouling release applications.
    Type: Grant
    Filed: October 9, 2009
    Date of Patent: January 14, 2014
    Assignee: NDSU Research Foundation
    Inventors: Dean C. Webster, Robert J. Pieper, Mohammed J. Nasrullah

  • Thermoset siloxane-urethane fouling release coatings
    Patent number: 7989074
    Abstract: A polymeric material may be prepared by reacting a mixture comprising an amino functional polyorganosiloxane, polyisocyanate, and polyol. The polyol may comprise a hydroxy-functional poly(meth)acrylate. The polymeric material may be used as a coating for a substrate and may inhibit fouling on a surface exposed to aquatic conditions.
