“…As a new membrane formation technology, our earlier studies [ 25 , 26 , 27 , 28 , 29 , 30 ] introduced a novel reverse thermally induced phase separation (RTIPS) technology. The RTIPS method combines a low membrane formation temperature with fast heat transfer.…”

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.

“…Studies have shown that PES membranes exhibit water ux in the range of 300-500 L m −2 h −1 bar −1 . 69,70 Therefore, PM-6 can show a water ux at the level of PES membranes, by virtue of pore activation aer isopropanol-water treatment. If it is to be compared with polymers used in membrane distillation, the example of PVDF and PTFE can be given.…”

“…Riedl et al (Riedl et al 1998) explained that a loose fouling layer was formed at the rough membrane surface causing lower ow resistance compare to smooth surface with dense fouling layers. Addition of P(MBAm-co-MAA) polymer particle increases the hydrophilicity of the membrane helps to attract water molecule compared to pristine M-0 membrane and thus lower contact angle improved the antifouling character of the membrane (Liu et al 2018a).…”

An effective single-step polymerization was followed for the synthesis of hydrophilicP(MBAm-co-MAA) microspheres. The distillation-precipitation polymerization (DPP) technique utilized N,N՛- methylenebis(acrylamide) (MBAm) as a crosslinker, methacrylic acid (MAA) as a monomer, solvent acetonitrile (ACN) and an initiator 2,2-azobisisobutyronitrile (AIBN) for synthesizing the P(MBAm-co-MAA) polymer particle.Simultaneously, in the reaction system, the polymer particles were formed as a precipitateand acetonitrile from the reaction was distilled out. The reaction takes placewithoutaddition of any surfactant or stabilizers. The morphology of the resultant microspheres, which were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), attenuated total reflectance fourier-transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA)and Brunauer-Emmett-Teller (BET) analysis.These microspheres were used as an additive for improving the performance of the fabricated membrane. The modified membranes showed increased hydrophilicity, porosity and water uptake.Membranes also exhibitedimproved permeability (63.7 Lh-1m-2bar-1), flux recovery ratio (80.7%)andthe highest protein rejection values of 94.8% (bovine serum albumin), 68.4% (pepsin), 86.9% (egg albumin) were observed. Therefore, the as-prepared membrane can potentially beusedfor protein removal from industrial wastewater.
