Preparation of Sodium Silicate Based Aerogels via Ambient Pressure Drying

Preparation of Sodium Silicate Based Aerogels via Ambient Pressure Drying 

A number of different strategies are known today, which can produce ambient dried silica aerogels from waterglass. Generally, one can distinguish  

Conventional gelation followed by solvent exchange and hydrophobization and 

Co-precursor methods. In the latter, the surface modification agent is added together with the silica precursor (waterglass) during gelation
