Abstract:
A method for producing a silica aerogel film by hydrolyzing and polymerizing alkoxysilane in the presence of a base catalyst to prepare an alkaline sol, adding an acid catalyst to the alkaline sol to carry out further hydrolysis and polymerization to prepare a first acidic sol, hydrolyzing and polymerizing alkoxysilane in the presence of an acid catalyst to prepare a second acidic sol, applying a mixture of the first and second acidic sols to a substrate, and drying it.
