Organic–inorganic hybrid charged membranes for proteins separation: Isoelectric separation of proteins under coupled driving forces

Functionalised activated carbon modified polyphenylsulfone composite membranes for adsorption enhanced phenol filtration

“…In recent years, inorganic materials have gained marked interest towards polymeric modification due to its low cost, high thermal stability and bio‐fouling resistance offered to the polymeric membranes. The organic–inorganic composite membrane tends to have a synergistic effect on filtration performance as better dispersion of inorganic components helps stronger bonding between organic and inorganic moieties . The addition of inorganic materials to organic polymers also helps to improve the permeability, removal efficiency and chemical and thermal resistance of polymeric membranes .…”

“…The organic-inorganic composite membrane tends to have a synergistic effect on filtration performance as better dispersion of inorganic components helps stronger bonding between organic and inorganic moieties. 2,3 The addition of inorganic materials to organic polymers also helps to improve the permeability, removal efficiency and chemical and thermal resistance of polymeric membranes. 4 Moreover, the trade-off between permeability and selectivity could be eliminated by suitable membrane modification using inorganic materials.…”

Functionalized chitosan derived novel positively charged organic–inorganic hybrid ultrafiltration membranes for protein separation

“…PVA) and functionalized polymers (phosphonated and quaternized chitosan) to fabricate organic-inorganic hybrid materials. 6,11,12,[19][20][21] PVA has been studied extensively as a membrane material due to its high hydrophilicity, excellent lm forming properties, low cost, commercial availability and chemical resistance as well as reactive functional groups for further cross-linking by irradiation, chemical, or thermal treatments. 22 Hybrid organic-inorganic membrane materials have been developed as a promising alternative to conventional organic or inorganic membrane materials.…”

Nanomembrane Canister Architectures for the Visualization and Filtration of Oxyanion Toxins with One‐Step Processing

“…The surface area ( S BET ), pore volume ( V p ), and pore diameter ( D ) of the hexagonal ONS were 120 m 2 g −1 , 0.2 cm 3 g −1 , and 3.7 nm, respectively. The established surface parameters and condensed fabrication of Al 2 O 3 @tubular SiO 2 /Al 2 O 3 with mesocylinder‐shaped pore connectivity in a hexagonal geometrical arrangement into canister MNTs are key factors to be considered in expanding PAA applications as a promising model for environmental membrane technologies …”

[42][43][44] High-resolution transmission electron microscopy (HRTEM) images were recorded along the perpendicular axis of the PAA channels ( Figure 3B);t he plane view of these micrographs showst he complete filling of the macroscopic disc (2.5 cm in Figure 3E) shows well-aligned NTst hat are oriented along the cavity channels of the PAA. The energy-dispersive X-ray spectroscopy for elemental mapping( STEM-EDS) of the canister SiO 2 /Al 2 O 3 MNTsi ndicates that the canister MNTsa re mainly composedo f Si (39.2 %), Al (11.9 %), and O( 48.9 %).…”
