Preparation and characterization of non-ionic block co-polymer templated mesoporous silica membranes

Template-assisted encapsulation of fluorinated silanes in silica films for sustained hydrophobic–oleophobic functionality

“…Samples for porosimetry were taken from freestanding films cast by evaporation of coating solutions and then calcined at 400°for 24 h. This treatment was done to remove residual organics while minimizing film densification through collapse of pores [39,40]. These samples were then degassed under vacuum at 120°C for 1 h prior to the adsorption.…”

Synthesis of ordered mesoporous silica membrane on inorganic hollow fiber

“…Generally, the porous ceramic substrates used for supports of mesoporous silica membranes are tubes [14,15] with diameters of at least several millimeters or flat disks [17][18][19]. Consequently, the resulting membranes have low surface area to volume ratios, typically a maximum of 100 m 2 m −3 in a membrane module.…”

Atomic Layer Deposition‐Modified Ordered Mesoporous Silica Membranes

“…Single-gas permeation was measured with helium and nitrogen at 25 -C under pressure drops between 300 and 1800 Torr. The hexane perm-porosimetry measurement apparatus and procedure is described in greater detail elsewhere [22]. Briefly, as the hexane vapor pressure is exposed to the membrane, capillary condensation occurs in the pores governed by the Kelvin equation.…”
