Influence of thermal process on microstructural and physical properties of ambient pressure dried hydrophobic silica aerogel monoliths

Ambient pressure dried hydrophobic silica aerogel monoliths were prepared via simultaneous solvent exchange and surface modification in order to minimize volume shrinkage and density. At room temperature, the obtained silica aerogels had a low density of 0.096 g/cm3, a high surface area and hydrophobicity, and ...

Synthesis and characterization of silica aerogel and its composite materials

Composite silica aerogels were prepared using sodium silicate and ceramics fibers. The thermal conductivities of these composites were investigated to determine how effective they would be as thermal insulation. As temperature increased to 400oC, the thermal conductivity of these composites only increased from 0.0266 to 0.0572 W/(...

Preparation and Characterization of Ultralow Density Silica Aerogels by Acetonitrile Supercritical Drying

Ultralow density silica aerogels were formulated by sol-gel process using tetramethyl orthosilicate as the precursor. A supercritical drying step was performed using acetonitrile solvent extraction. These aerogels were found to have a high specific surface area (~812m2/g) and they were found to be excellent ...

Preparation of silica aerogel/polyurethane composites for the application of thermal insulation

The authors prepared silica aerogel/polyurethane composites by two different methods for the comparison of the two methods. The objective was to study the thermal insulation and hydrophobic properties of the composites to evaluate their potential for use as fabric membranes. It was found that ...
