High performance polyamide composite nanofiltration membranes via reverse interfacial polymerization with the synergistic interaction of gelatin interlayer and trimesoyl chloride

Porous Gelatin Membranes Obtained from Pickering Emulsions Stabilized with h-BNNS: Application for Polyelectrolyte-Enhanced Ultrafiltration

“…The water flux obtained in this work is higher than the flux obtained by gelatin-based membranes already presented in the literature. Polyamide (PA) thin film nanofibrous composite membranes with a polyacrylonitrile (PAN) substrate and gelatin interlayer fabricated by reverse interfacial polymerization (IP-R) display a flux of 135.6 L m −2 h −1 [ 51 ], whereas gelatin membranes previously prepared in our group using Pickering emulsion method but with graphene oxide (GO) as stabilizer and ethyl benzoate as oil phase were characterized with a quite low water permeability of 5.8 ± 1.3 L m −2 h −1 bar −1 [ 52 ]. The complexation–ultrafiltration tests were carried out using the BNG-5 h-12 h membrane, and its L p value (150 L h −1 m −2 bar −1 ) was considered the reference value to assess concentration polarization and membrane fouling.…”

Preparation of a novel zwitterionic striped surface thin-film composite nanofiltration membrane with excellent salt separation performance and antifouling property

“…35 The specic absorption peaks at 1658 cm À1 and 1530 cm À1 were attributed to the existence of the formation of -C]O (amide I and amide II). 36,37 With the increase in the concentration of taurine, the intensity of this peak was decreased. The band appearing in the M b and M 2 membrane spectra at 1645 cm À1 was assigned to the formation of the -C] Fig.…”

2D nanosheet enabled thin film nanocomposite membranes for freshwater production – a review

“…In addition, the size and characteristics of nanosheets might be altered due to the spraying effect. Alternative options such as support-free IP technique, 134 reverse IP technique, 135,136 stitching of nanosheets prior to IP reactions 100 and nanosheets interlayer 43 from difficulties to attach or transfer the fabricated fragile PA layer onto the support membrane. Reverse IP is similar to the conventional IP technique with the sequence of contacting the aqueous and organic phase reversed.…”
