Cellulose acetate butyrate membrane containing TiO2 nanoparticle: Preparation, characterization and permeation study

Preparation and characterization of a novel hydrophilic PVDF/PVA/Al2O3 nanocomposite membrane for removal of As(V) from aqueous solutions

“…As obvious, nanoparticles increase finger‐like pores to a certain degree and then reduce it. The same behavior has also been reported in other studies . It is shown that for NCM‐1 to NCM‐3 membranes, which contain lower concentrations of Al 2 O 3 nanoparticles in comparison to NCM‐4 and NCM‐5, the membranes have become more porous with stretched finger‐like macropores; however, the porosity reduces relatively for NCM‐4 and NCM‐5 with higher Al 2 O 3 contents.…”

Chitosan/polyvinyl alcohol/amino functionalized multiwalled carbon nanotube pervaporation membranes: Synthesis, characterization, and performance

“…Strategies including blending, 1,[7][8][9][10][11][12][13][14][15][16] crosslinking, 14,[17][18][19][20][21][22][23][24][25] and filling 5,10,12,22,23,[25][26][27][28][29][30][31][32][33] are often used to improve the membrane properties such as hydrophobicity-hydrophilicity equilibrium, permeability, selectivity, and thermal/mechanical stability. These improvements occur through altering the bulk properties of the membrane such as mobility of functional groups or polymer chains as well as the degree of crystallinity.…”

Effects of Gelatin and Nano‐ZnO on the Performance and Properties of Cellulose Acetate Water Membranes

“…However, due to the presence of hydrophilic nanoparticles, it strengthened the thermodynamic instability, which overcame the viscosity at low-to-moderate gelatin contents. Conversely, at high gelatin contents, the effect of viscosity prevailed that of nonsolvent [35].…”
