| Abstract | Nanoporous silica cryogels with a high specific surface area of 1095m(2) g(-1) were fabricated using tert-butyl alcohol as a reaction solvent, via a cost-effective sol-gel process followed by vacuum freeze drying. The total time of cryogel production was reduced markedly to one day. The molar ratio of solvent/precursor, which was varied from 5 to 13, significantly affected the porous structure and thermal insulating properties of the cryogels. The silica cryogels with low densities in the range of 0.08-0.18 g cm(-3) and thermal conductivities as low as 6.7mW(m.K)(-1) at 100 Pa and 28.3mW(m.K)(-1) at 10(5) Pa were obtained using this new technique. |
