Preparation and characterization of phosphorylated Zr-doped hybrid silica/PSF composite membrane

The effects of thermally stable titanium silicon oxide nanoparticles on structure and performance of cellulose acetate ultrafiltration membranes

“…As shown in this Hence, by embedding 20 wt% of TiSiO 4 nanoparticles in CA/TiSiO 4 blend composition the static water contact angle of the membrane was reduced to the lowest due to the presence of -OH functional groups of hydrophilic titanium silicon oxide nanoparticles well dispersed in the membrane [17]. The satisfactory improvement in membrane hydrophilicity with increased incorporation of TiSiO 4 nanoparticles in the membrane matrix can also be attributed to the point defects in the nanoparticles embedded therein [31]. This improved hydrophilicity is comparable to that of various other blend membranes reported by earlier studies [21].…”

Fabrication of polyethersulfone-mesoporous silica nanocomposite ultrafiltration membranes with antifouling properties

“…However, increasing the MS amount to more than 2% does not further improve membrane hydrophilicity. Zhang et al also reported the similar results [30].The possible reason was that the aggregation of the MS particles occurred on the membrane surface when the MS content was further increased to 4% in the membrane. Overall, the membrane with 2% MS (M2) had the best hydrophilicity due to the well dispersed hydrophilic mesoporous silica in the membrane, which is expected to result in high antifouling performance of the membrane.…”

Nano-structure construction of porous membranes by depositing nanoparticles for enhanced surface wettability

“…For the hydrophilic membrane, many studies related to modification of membrane for improving the membrane surface hydrophilicity have been reported. One method is to blend the membrane matrix with inorganic nanoparticles, which could help to improve the membrane hydrophilicity and as a result could increase the water permeability [8][9][10]. Another strategy is to modify the membrane surface by introducing hydrophilic polymer to improve the surface hydrophilicity [7,[11][12][13].…”
