  • SURFACES AND COATING COMPOSITIONS HAVING ANTIFOULING, ANTITHROMBOTIC, AND ANTIBACTERIAL PROPERTIES AND METHODS OF MAKING
    Publication number: 20230053808
    Abstract: Coating compositions, coated articles including the coating compositions, and methods of making the coating compositions and coated articles are provided. In some aspects, the coating compositions are applied to a substrate having nitric oxide-releasing properties. The coating compositions can include copolymers having crosslinking agents that can be activated with mild UV light (about 345 nm to 365 nm) to avoid damaging the substrate while creating strong covalent bonds to the substrate. The copolymers can include hydrophilic repeat units, and in particular zwitterionic repeat units such as repeat units containing phosphorylcholine groups. In some aspects, the coating compositions are applied to a surface of a polymer substrate, wherein the polymer substrate had nitric oxide releasing properties. The coating compositions and the coated articles can have antifouling, antithrombotic, and/or antibacterial properties.

  • Surfaces having antifogging characteristics, coating compositions having antifogging characteristics, and methods of making antifogging surfaces
    Patent number: 11161926
    Abstract: Articles having anti-fogging characteristics, coating compositions providing anti-fogging characteristics, and methods for applying coating compositions with anti-fogging characteristics are described. The coating compositions give a surface or article an anti-fogging characteristic. Articles having such anti-fogging characteristics include those having optical clarity, such as eyewear.
