Effect of the thermal treatment on microstructure and physical properties of low-density and high transparency silica aerogels via acetonitrile supercritical drying

Silica aerogels have extremely low thermal conductivities, potentially making them effective thermal insulators. In this study, the thermal conductivities of various samples were explored using the Transient Plane Source (TPS) Method. Samples of the silica aerogels were approximately 1.3 cm thick and between 4.1-4.3 cm in ...

Assembly of silica aerogels within silica nanofibers: towards a super-insulating flexible hybrid aerogel membrane

Silica aerogels (SA) are identified as one of the most advanced thermal insulating materials to date, however, their range of applications is limited due to a high sensitivity to moisture and issues with brittleness. This study highlights the design and fabrication of a new and ...

Novel lightweight and highly thermally insulative silica aerogel-doped poly (vinyl chloride)-coated fabric composite

In this research silica aerogels were incorporated into PVC fabrics by the research team to improve the overall performance of the fabrics. The aerogel was added in percent fractions of 0, 2, 3, and 4%. Comprehensive analysis of physical and mechanical properties was also performed. Thermal conductivity measurements revealed ...

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 ...

The influence of gaseous heat conduction to the effective thermal conductivity of nano-porous materials

The effective thermal conductivity of a commercial silica aerogel is determined at various gas pressures ranging from 0.001 Pa to 1 MPa in order to determine the contribution of gaseous heat conduction to the effective thermal conductivity of nano-porous materials. It was determined that the gas pressure ...
