Title:
含フッ素基修飾ポリシルセスキオキサン液体、含フッ素基修飾ポリシルセスキオキサンガラス及びこれらの製造方法
Document Type and Number:
Japanese Patent JP6411008
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a low-refractive-index, low-dispersion, low-density fluorine-containing group-modified polysilsesquioxane glass excellent in terms of ultraviolet transparency, low-temperature moldability, and heat resistance and capable of forming a thin film; a fluorine-containing group-modified polysilsesquioxane liquid serving as a precursor of the fluorine-containing group-modified polysilsesquioxane glass; and methods for easily manufacturing both.SOLUTION: The provided method for manufacturing a fluorine-containing group-modified polysilsesquioxane glass includes steps of hydrolyzing and poly-condensing a mixture consisting of a fluorine-containing group-modified trifunctional silicon alkoxide, water, and an acid catalyst without using an organic solvent as a co-solvent, removing the alcohol generated as a result of the hydrolysis of the fluorine-containing group-modified trifunctional silicon alkoxide, and performing a heat treatment.
