Synthesis and pore analysis of aerogel–glass fiber composites by ambient drying method

Preparation of SiO2 nanocomposites with aligned distributing glass fibre using freeze-drying process

“…The GF-R composites with 10 and 20 wt.% of glass fibres have the mean pore sizes of 9.6 and 12.5 nm, respectively. Thus, both GF-A and GF-R are ascribed as mesoporous materials [15]. Likewise, the pore size distribution of the GF-R is similar with that of the GF-A composites, indicating that the pore size distribution of this composite is not dependent on the doping content of glass fibres as well as on the preparation.…”

Synthesis of silica aerogel blanket by ambient drying method using water glass based precursor and glass wool modified by alumina sol

“…It is thought that density and porosity of aerogel blanket is strongly related with its microstructure, which is affected by precursor, catalyst, drying condition and surface modification [25].…”

“…Aging by adding additional monomer before or after the gel point is also known from the sodium silicate/silica system [22]. Recently Kim et al [25] synthesized water glass based aerogels-glass fiber composites by ambient pressure drying without modification of glass wool. They synthesized silica aerogel-glass fiber composites with a minimum density of 0.116 g/cm 3 and maximum porosity of 90.8.…”

Stability of Nanoporous Silica Aerogel Dispersion as Wettability Alteration Agent

“…[4] Silica aerogel (SA) is a classic example of developing amorphous nanoporous materials which have applications in industries commercially, and many new applications under development. [5][6][7][8][9][10][11][12] Unique properties of SA such as large surface area, very low density, controllable hydrophilic or hydrophobic surface, stable properties up to 450 C and high porosity, enable their use as a wettability alteration agent in enhanced oil recovery (EOR) processes. [13] Wettability alteration of reservoir rock surface is one of the promising technologies for EOR.…”
