EFFECT of IONIC LIQUID CONTENT on MONOLITHIC STRUCTURE of AMINE-MEDIATED SILICA AEROGEL via AMBIENT PRESSURE DRYING
Abstract
In
this study, amine-mediated silica aerogels dried under the ambient conditions
in monolithic form were prepared by following sol-gel method.
3-aminopropyltriethoxysilane (APTES) was involved to the synthesis as a silica
co-precursor. Imidazolium based short-chain ionic liquids (ILs) were
incorporated into the silica gel structure to control the gel shrinkage within
the pores, as well as to eliminate the capillary effect during the solvent
evaporation. A production procedure was developed to explore the synergistic
effect of ionic liquids and amine functionalized silica precursor on the
textural and chemical properties of the final silica gels. Surface
modifications of the samples were performed by using
3-Methacryloxypropyltrimethoxysilane (MEMO) to ensure hydrophobic
characteristics. To reveal the chemical and morphological characteristics of
the resultant material, various analyses were conducted. SEM and FTIR analyses were performed to
investigate the morphological and chemical structure, whereas TGA analysis was
carried out to determine the thermal stability of the silica gels. As a result,
ionic liquid embedded sample was obtained in a monolithic structure with a low
density (0.45 g/cm3) and had a good thermal stability (up to 381 °C). Contact
angle measurement also demonstrated that the desired monolithic sample has
hydrophobic characteristic with a water contact angle value of 113˚.
