Thermal behavior and structural study of SiO2/Poly(ε-caprolactone) hybrids synthesized via sol-gel method [PDF]

, 2018
SiO2-based organic-inorganic hybrids (OIHs) are versatile materials whose properties may change significantly because of their thermal treatment. In fact, after their preparation at low temperature by the sol-gel method, they still have reactive silanol ...

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

, 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.
