A process for the preparation of kinetically stable semiconductor/polymer nanodispersion whereby the aqueous stability of the dispersed photocatalysts and polymer latex particles are ensured by the high surface charge. Consequently, the thin photocatalytically active antimicrobial coating prepared from this electrostatically stabilized aqueous dispersion by spray-coating method contains well-dispersed and evenly distributed surface photocatalyst particles immobilized by polymer and thus it provides homogeneous, transparent and mechanically stable photoreactive and antimicrobial thin film on arbitrary surfaces.

This application features a method of forming a nanoporous layer. The method includes steps of dispensing on a substrate a colloid composition comprising a liquid and a number of nanoparticle clusters, and subjecting the dispensed colloid composition to drying to form the nanoporous layer over the substrate. The nanoporous layer includes nanoparticles deposited to form a three dimensional network of irregularly shaped bodies. The nanoporous layer also includes a three dimensional network of irregularly shaped spaces that are not occupied by the three dimensional network of irregularly shaped bodies.

The present invention relates to a pigmented matte coating composition comprising an aqueous dispersion of a) phosphorus acid functionalized polymer particles; b) TiO.sub.2 particles; c) polymeric organic microspheres; and d) a rheology modifier. The composition of the present invention gives matte finish coatings having the stain and scrub resistant attributes similar to coatings formed from semi-gloss paint compositions.

A superhydrophobic coating is provided and contains organosilane, an inorganic nanomaterial, and an emulsifying agent. A mass proportion of the components is controlled, so that the superhydrophobic coating can form a micro-nano mixed microstructure inside foam concrete. The organosilane first forms dense hydrophobic surface layers on the surface and in inner pores of the foam concrete, and the nanomaterial forms uniformly distributed nano-bulges on the hydrophobic surface layers formed by the silane. The superhydrophobic performance of the foam concrete can be effectively improved by combining the two microstructures. The foam concrete exhibits excellent superhydrophobic performance.

Articles including durable and icephobic and/or biocidal polymeric coatings are disclosed. The polymeric coatings can include a bonding layer which may contain a substantially fully cured polymeric resin providing excellent adhesion to metallic or polymer substrates. The polymeric coating further includes an outer surface layer which is smooth, hydrophobic, biocidal and icephobic and, in addition to a substantially fully cured resin, contains silicone comprising additives near the exposed outer surface. The anisotropic polymeric coatings are particularly suited for strong and lightweight parts required in aerospace, automotive and sporting goods applications. A process for making the articles is disclosed as well.
