摘要

从原位共聚和后处理两个方面着手，介绍了近年来国内外硅气凝胶疏水改性的研究进展；再从疏水SiO₂气凝胶的特殊性能出发，简要介绍了其在隔热、催化、吸附等技术领域的研究进展。

Abstract

Setting about in-situ copolymerization and post-treatment methods,the research progress on hydrophobic modification of silica aerogels in the world in recent years is introduced.From the special properties of hydrophobic silica aerogels,the research progress in its application in the fields of heat insulation,catalysis and adsorption is briefly introduced.
