Abstract
A silica aerogel coating is produced by reacting a wet gel obtained by the hydrolysis and polymerization of alkoxysilane with an organic-modifying agent to form organically modified silica, dispersing the organically modified silica by an ultrasonic treatment to form an organically modified silica dispersion, adding an ultraviolet-curable resin and a photo-polymerization initiator to the dispersion to prepare a coating liquid, applying the coating liquid to a substrate, and then irradiating ultraviolet rays to the coated layer.
