  • Patent number: 11891486
    Abstract: The disclosure relates to sidechain functionalized organosiloxane compounds comprising polyalkyleneoxide (POA) and/or polyalkyleneoxide coupled zwitterionic moieties with various other modular side chains including reactive and or non-reactive groups. The present disclosure further also pertains to ice-phobic polymer formulations capable of curing on a substrate to form a surface that is ice-phobic, resistant to ice formation, and/or resistant to ice adhesion. The disclosed ice-phobic polymer formulations comprise one or more disclosed sidechain functionalized organosiloxane compound, one or more binder resin, and/or one or more lubricating liquid. The present disclosure further relates to articles comprising the disclosed ice-phobic polymer compositions, thereby providing articles having ice-phobic properties. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

  • Patent number: 11542409
    Abstract: The present teachings generally provide curable polysiloxane compositions including a base resin including a surface active polymer. Articles of manufacture including the curable polysiloxane compositions and slippery coatings and materials also are provided. The compositions may be used to provide slippery, lubricious, or repellent materials and coatings and may provide anti-fouling function. The compositions can provide anti-fouling or foul-release function on open surfaces, internal surfaces, membranes; to provide pinning free or low contact angle hysteresis surfaces; to provide homogeneous interface to suppress nucleation; to provide a barrier layer such as anti-corrosion; to provide anti-stain, anti-smudge, anti-fingerprint, anti-soil function.

  • Publication number: 20210269464
    Abstract: A variety of polyoxyalkylene coupled zwitterionic moieties are provided as well as surface active reactive polymers containing the polyoxyalkylene coupled zwitterionic moieties. When incorporated in coating systems, such surface active polymers show strong propensity to stratify during curing. The zwitterionic groups presented at the end of polyalkylene oxide chains can allow for effective exposure of the zwitterionic groups at the coating/water interface as the polyoxyalkylene side chains of the said SAP can further extend (to its radius of gyration) into the water phase. Additional features of the polyoxyalkylene coupled zwitterionic moieties can include a reactive end group (R) to allow covalent attachment of the moiety to a surface, a particle, a small molecule, or a polymer. Coating compositions and coated articles containing the polyoxyalkylene coupled zwitterionic moieties are also provided.
