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
