摘要:

二氧化硅气凝胶以其独特的纳米孔结构展现出优异的性能,并在很多领域得到较好的应用。选择不同的硅源既有成本因素,又有性能要求,总的原则是优化气凝胶的结构和性能,拓展其应用领域。单一硅源主要有水玻璃和各种硅醇盐。复合硅源则可以引入疏水性和功能性基团,从而使二氧化硅气凝胶的结构性能得到改善,制备工艺过程更为优化。对二氧化硅气凝胶硅源选择的研究现状和前景做了系统探讨。

关键词: 气凝胶, 二氧化硅, 硅源, 疏水基团, 功能基团

Abstract:

Silica aerogel exhibits excellent performance with its unique nanopore structure and has good application in many fields.Choosing different silicon sources has both cost factors and performance requirements.The general principle is to optimize the structure and performance of silica aerogel and expand its application fields.A single silicon source is mainly water glass and silanol salts.The composite silicon source can introduce hydrophobic and functional groups,so that the structure and properties of silica aerogel can be improved and the preparation process can be more optimized.Finally,the research sta tus and prospect based on silicon source selection of silica aerogel were discussed emphatically.

Key words: aerogel, silica, silicon source, hydrophobic group, functional group
