A coating composition is disclosed. The coating composition includes a poly(methyl methacrylate) polymer or copolymer having a weight average molecular weight of at least 50,000 grams per mole; monomer comprising at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate, wherein the at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate provides at least 80 percent by weight of the monomer; and a stabilizer against ultraviolet light. An article including a coating on a surface of a substrate and a method of making the article are also disclosed. The coating on the surface of the substrate is obtained by curing the disclosed coating composition.

Articles having poly(vinyl alcohol) (PVA) and silica nanoparticle multilayer coatings are provided. More specifically, the articles include a substrate and a multilayer coating attached to the substrate. The multilayer coating includes a silica layer that is the outermost layer, the silica layer containing acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. The multilayer coating also includes a PVA layer disposed between a surface of the substrate and the outermost silica layer. The PVA and silica nanoparticle coatings can be used on a large variety of substrates and tend to be resistant to impacts, scratches, wet abrasions, soil and fog.

Poly(vinyl alcohol) and silica nanoparticle multilayer coatings and methods

Articles having crosslinked poly(vinyl alcohol) (PVA) and silica nanoparticle multilayer coatings are provided. More specifically, articles including a substrate, and a multilayer coating attached to the substrate are provided. The multilayer coating includes a first crosslinked poly(vinyl alcohol) (PVA) layer and a first silica layer. The first crosslinked PVA layer is an outermost layer of the multilayer coating. The first silica layer comprises a plurality of acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. The PVA and silica nanoparticle multilayer coatings can be used on a large variety of substrates and tend to be resistant to wet and dry abrasions, scratches, and impacts.

Hydrophilic articles and methods of using such articles are described. The hydrophilic articles include a hydrophilic layer comprising sintered, acidified silica nanoparticles attached to a substrate. A spacer layer attached to a first portion of the hydrophilic layer defines at least one fluid transport channel bounded on one side by a second portion of the hydrophilic layer. The nanoparticles may include one or both of spherical and elongated nanoparticles.
