Intensification of mass transfer for zwitterionic amine monomers in interfacial polymerization to fabricate monovalent salt/antibiotics separation membrane

Zwitterionic groups are conducive to improve the antifouling performance and water permeability of nanofiltration membranes because of the excellent hydrophilicity and charged property. However, the transport of zwitterionic monomers during interfacial polymerization process is much slower than the reaction, leading to form many defects in the separation layer. In this study, phase transfer catalysts were used to intensify the interfacial mass...
