“…It is a simple and effective way to improve hydrophilicity of PES membrane. Many investigations have successfully prepared hydrophilic PES membranes by blending hydrophilic material with PES [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Heru et al [ 18 ] prepared PES ultrafiltration membranes by NIPS method using polyvinylpyrrolidone (PVP), poly(ethylene glycol) (PEG) and poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (Pluronic) as macromolecular additives.…”

“…Their results showed that Pluronic possesses the best behavior across all properties. Han et al [ 21 ] prepared Mg(OH) 2 /PES hybrid membranes by in-suit synthesized phase inversion method, and the results showed that nano-sized Mg(OH) 2 was formed and distributed uniformly in PES matrix membrane. With the increase of Mg(OH) 2 content, the membrane’s hydrophilicity, porosity, and permeation flux improved.…”

Sulfonated polyethersulfone (SPES) was used as an additive to prepare hydrophilic poly(ethersulfone) (PES) hollow fiber membranes via non-solvent assisted reverse thermally induced phase separation (RTIPS) process. The PES/SPES/N,N-dimethylacetamide (DMAc)/ polyethylene glycol 200 (PEG200) casting solutions are lower critical solution temperature (LCST) membrane forming systems. The LCST and phase separation rate increased with the increase of SPES concentrations, while the casting solutions showed shear thinning. When the membrane forming temperature was higher than the LCST, membrane formation mechanism was controlled by non-solvent assisted RTIPS process and the also membranes presented a more porous structure on the surface and a bi-continuous structure on the cross section. The membranes prepared by applying SPES present higher pure water flux than that of the pure PES membrane. The advantages of the SPES additive are reflected by the relatively high flux, good hydrophilicity and excellent mechanical properties at 0.5 wt.% SPES content.

“…This nding is consistent with other reported studies. 7,29 During the phase inversion process in water environment, the hydrophilic moieties can migrate from the polymer bulk to the interface of water/polymer, and then leach out from surface layer to coagulation bath. 22 In this study, the additional positive Y 3+ cations easily migrate from polymer bulk to membrane surface and further to coagulation bath in phase inversion process.…”

Phase separation temperature estimations, based on Hansen solubility parameters for poly(ethersulfone) (PES)/solvent/non-solvent systems, were carried out to study the control of phase separation temperature in a reverse thermally induced phase separation (RTIPS) process. Four membrane-forming systems were studied, namely PES/N,N-dimethylacetamide (DMAc)/diethylene glycol (DEG), PES/DMAc/polyethylene glycol 200 (PEG200), PES/DMAc/PEG300 and PES/DMAc/PEG400. The effects of PES molecular weights, PES concentrations, PEG molecular weights and ratios of non-solvent/solvent on phase separation temperature are investigated, and the theoretical Hansen solubility parameter calculation is used to establish a prediction equation for phase separation temperature. A linear relationship between the experimental data and the difference in the 2 solubility parameters between PES and the mixed solvent was observed. When the membrane-forming temperature was higher than the cloud point, membranes with a bi-continuous structure were acquired and showed a higher pure water permeation flux than that of membranes prepared with the non-solvent induced phase separation (NIPS) process. The pure water permeation flux and the mean pore size of membranes prepared with the RTIPS process decreased in line with an increase of PES molecular weight. When the membrane formation mechanism was the RTIPS process, the mechanical properties were better than those of the corresponding membranes prepared with the NIPS process. Highlights> A group contribution estimate of phase separation temperature for RTIPS was proposed.> Phase separation temperatures were linearly dependent on Hansen solubility parameters.> PES membranes with bi-continuous structure were acquired from RTIPS process. > PES membranes prepared by RTIPS showed good permeation and mechanical properties.
