    Abstract: A method of making a coatable composition includes: providing a first composition comprising silica nanoparticles dispersed in an aqueous liquid vehicle, wherein the first composition has a pH greater than 6; acidifying the first composition to a pH of less than or equal to 4 using inorganic acid to provide a second composition; and dissolving at least one metal compound in the second composition to form the coatable composition. The silica nanoparticles have a polymodal particle size distribution, wherein the polymodal particle size distribution comprises a first mode having a first particle size in the range of from 8 to 35 nanometers, wherein the polymodal particle size distribution comprises a second mode having a second particle size in the range of from 2 to 20 nanometers, wherein the first particle size is greater than the second particle size. Coatable compositions, antistatic compositions, preparable by the method are also disclosed. Soil-resistant articles including the antistatic compositions are also disclosed.

    Abstract: A method of making a coated article is described comprising providing an inorganic substrate and coating the substrate with a coating composition. The coating composition comprises a plurality of siloxane nanoparticles dispersed in an organic solvent. A portion of the nanoparticles comprise the reaction product of a first alkoxy silane compound having a first organofunctional group and a second organofunctional group of a second compound and the reaction between the first and second organofunctional groups form an organic linking group. The method further comprises drying the coating composition and heating the coated substrate to volatilize the organic linking groups thereby forming a porous surface layer on the inorganic substrate. In another embodiment an article is described comprising an inorganic substrate, such as glass, and a porous inorganic (e.g. silica) surface layer having an average pore size of less than 30 nm. Also described are coating compositions and methods of making a nanoparticle coating compositions.
