Abstract:
A writeable-projectable glass board (100) comprising a glass substrate (110) provided with a light-diffusion coating (140) on one surface (120) and a matte surface (150) on the other surface (130) is provided. An air-gap (160) is defined between the surface of the glass substrate (130) and matte surface (160). The light-diffusion coating (140) provides excellent writability, erasability and hot-spot (glare) free sharp projection of images. The matte surface (150) reduces the halo image formation and thereby enhances projection sharpness. The air-gap (160) provides visibility of the projected images with high quality from wide angle of view.

Abstract:
The present invention provides a layered coating adhered to a substrate surface which conforms to a surface topography defined by the anisotropic chain-like silica nanoparticles on the substrate. The layered coating comprises a layer of anisotropic chain-like silica nanoparticles. The anisotropic chain-like silica nanoparticles comprise linked arrays of silica net-negatively charged nanoparticles, each linked array having at least one linear dimension of about 100 nm to about 1200 nm and the anisotropic chain-like silica nanoparticles each have a diameter of about 20 nm to about 80 nm. The substrate surface comprises surface active moieties carrying a net positive charge and the chain-like anisotropic silica nanoparticles are held to the surface by electrostatic charge. Advantageously, the layered coatings are transparent and superhydrophobic. Also provided are articles containing these layered coatings.
