Reflectance reducing film and method of forming same on glass substrate

摘要: The invention relates to a reflectance reducing silicon dioxide film formed on glass substrate by the sol-gel process. To make minutely rough, at least two sols are respectively prepared from one compound selected group consisting of alkoxides and acetylacetonates, such that polymers have different average molecular weights. Then, mixed with solvent so as prepare coating solution. solution is applied form sol substrate. thus coated heated transform into gel film. which rough satisfactory in reduction.
