SANS study of hybrid silica aerogels under "in situ" uniaxial compression [PDF]

open access: yes, 2008
We have modified the inorganic silica network of aerogels with polydimethylsiloxane (PDMS), a hydroxyl-terminated polymer, to obtain an organic modified silicate (ORMOSIL). Reactions were assisted by high-power ultrasounds.
