Incorporation of carboxylic monoamines into thin-film composite polyamide membranes to enhance nanofiltration performance

Sulfaguanidine nanofiltration active layer towards anti-adhesive and antimicrobial attributes for desalination and dye removal

“…The C 1s component peaks at binding energy of 284.2, 285.4 eV and 287.6 ( Fig. 3d and f) are assigned to C]C/C-C, N-C]O and C-N, respectively, 48,49 while N 1s component peaks at 399.4 eV and 399.9 eV ( Fig. 3e and g) are assigned to N-C]O and C-N, respectively.…”

“…These results signify that an NF membrane with unprecedentedly high water permeance and a satisfactorily high rejection salt rejection was achieved via the CASIP procedure. The ltration performance regarding permeance and salt rejection of SG-0.3 membrane is also compared with those of several commercial and other stateof-the-art NF membranes reported recently in literatures, 7,16,47,48 (ESI ref. 1-8 †) which are summarized in Fig.…”

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.…”

High-Performance Polyacrylic Acid-Grafted PVDF Nanofiltration Membrane with Good Antifouling Property for the Textile Industry

“…To date, several modifications have been proposed to prepare highly selective NF membranes with good antifouling property, such as interfacial polymerization, self-assembly of polyelectrolyte, polymer coating, and UV-grafting [ 6 ]. Interfacial polymerization (IP) is the most common technique employed for producing a commercial thin-film composite (TFC) membrane [ 8 , 20 ]. Within a short reaction time, a thin and dense selective layer can be acquired.…”
