This paper shows the chemistry, process, and properties of the particulate and non-particulate polyether-based hybrid silica aerogels. The non-particulate, continuous polyether-based aerogel has superior mechanical properties and a similar insulation property compared to the particulate one. The non-particulate aerogel processing does not require aging, and the gelation time is also shortened significantly. Consequently, the processing time is dramatically decreased for non-particulate polyether-based aerogel, indicating scalability. It is believed that spinodal decomposition occurred for non-particulate aerogel processing whereas binodal decomposition occurred for particulate aerogel processing.
