Abstract
Methods for producing a silica aerogel coating by: producing a wet gel formed by the hydrolysis and polymerization of an alkoxysilane having an ultraviolet-polymerizable unsaturated group; organically modifying the wet gel with an organic-modifying agent to obtain an organically modified silica having a modification ratio of 10-30% based on a total amount of Si—OH in the wet gel; coating a dispersion of the organically modified silica on a substrate to form a layer; and subjecting the layer of the organically modified silica to ultraviolet irradiation and baking, wherein the silica aerogel coating includes the organically modified silica and wherein the silica aerogel coating has a refractive index in the range of 1.05-1.2.
