Abstract: 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.

Abstract: The present invention provides a hydrophilic film that causes a liquid to diffuse rapidly in a single direction. The hydrophilic film comprises a substrate having a texture of parallel sunken and raised patterns, and a hydrophilic coat comprising a coat of silicon dioxide particles. The present invention also provides a method for preparing the hydrophilic film. The method comprises: preparing an aqueous dispersion of silicon dioxide particles, wherein the average size of the silicon dioxide particles is 1 to 60 nm, and the concentration of the silicon dioxide particles is 0.05% to 15% by weight; coating the aqueous dispersion of silicon dioxide particles on a substrate, wherein the substrate has a texture of parallel sunken and raised patterns; and drying the substrate coated with the aqueous dispersion of silicon dioxide particles.
