Abstract: Coating compositions are described including silica nanoparticles functionalized with an alkenyl silane, a dispersing agent, and a compound including a polyethylene oxide segment containing at least one hydroxyl group, at least one silane, and optionally a hydrophobic group. The coating compositions further include at least two multifunctional (meth) acrylate monomers. Also described are articles including the dried and cured coating composition disposed on a substrate. The articles exhibit anti-fog characteristics and often also mechanical durability.

Abstract: A fluoropolymer coating composition is described comprising an aqueous liquid medium, fluoropolymer particles dispersed in the aqueous liquid medium, and at least one aziridine compound. The aziridine compound comprises at least two aziridine groups (i.e. polyaziridine) or at least one aziridine group and at least one alkoxy silane group. In another embodiment, an article is described comprising a substrate wherein a surface of the substrate comprises a coating comprising fluoropolymer particles; and a reaction product of at least one aziridine compound comprising at least two aziridine groups or at least one aziridine group and at least one alkoxy silane group. The coating can be utilized as a primer for bonding a non-fluorinated substrate to a fluoropolymer film and/or the coating can be used as an (e.g. outer exposed) surface layer. In some embodiments, the article may be the (e.g. backside) film of a photovoltaic module.

Abstract: A composition is described comprising at least one fluoropolymer. The fluoropolymer comprises at least 90% by weight based on the total weight of the fluoropolymer of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers and a fluorinated additive having a Mw of no greater than 50,000 g/mole comprising a partially fluorinated or perfluorinated alkyl or ether group. In some embodiments, the composition further comprises a fluorinated solvent. Also described are substrates comprising a coated surface of the fluoropolymer composition described herein.

Abstract: Polyurethane/urea nanocomposites, precursors thereof, and methods of their manufacture and use are provided, the nanocomposites comprising: a) a polyurethane/urea polymer matrix, and b) surface modified silicon carbide nanoparticles dispersed within and covalently bound to a polyurethane/urea polymer comprising the polyurethane/urea polymer matrix. In some embodiments, the surface modified silicon carbide nanoparticle comprises a silicon carbide core and a linking group covalently bound to the surface of the silicon carbide core and covalently bound to the polyurethane/urea polymer. In some embodiments, the linking group is a moiety according to Formula where the urethane group of the linking group is covalently bound to the polyurethane/urea polymer; and where each open valence of the silicon atom of the linking group is bound to a hydroxyl group (—OH) or is covalently bound to the surface of the silicon carbide core through an oxygen atom.
