Abstract (en)
[origin: WO2017185009A1] A method of synthesizing aerogels and cross-linked aerogels are described that incorporate freeze-drying in lieu of supercritical solvent drying. Advantages over supercritical drying include a reduction in hazard risks posed by drying at supercritical conditions as well as the ability to up-scale the process to accommodate large pieces of material without introducing risk. In addition, inexpensive and more sophisticated mold technologies, which are not impervious to supercritical conditions, can be used to produce aerogel materials according to the freeze-drying method of the invention. This introduces a level of freedom never before available for the production of aerogel components.
