Insights on the Influence of the Drying Method and Surface Wettability on the Final Properties of Silica Aerogels.

In fact, the percentage reduction in pore size when drying by freeze-drying in comparison to HT and LT-SCD followed a clear trend; less hydrophobic samples presented a higher pore reduction because of the higher surface energy; for instance, for 100T aerogel, these reductions were by ca. 80% with respect to both SCD techniques.
