“…The obtained results as shown in Table , clearly indicate that the surface roughness of the fabricated membrane increase with increase in SCER content. It has been reported that membranes with lower surface roughness have stronger antifouling abilities . The fouling capability tends to increase with increase in surface roughness due to accumulation of solute in the node of the rough membrane surface .…”

“…It has been reported that membranes with lower surface roughness have stronger antifouling abilities. [45][46][47] The fouling capability tends to increase with increase in surface roughness due to accumulation of solute in the node of the rough membrane surface. 46 Hence the fabricated membrane with low value of SCER were expected to have better antifouling resistances.…”

In this study, antifouling membranes were prepared through dry wet‐phase inversion method. The incorporation of electrostatistically charged group of sulfonate cation exchange resins (SCER) into polyethersulfone membrane matrix attempts to give a synergistic combination of properties for bovine serum albumin (BSA) removal. The effect of different composition of SCER into the blend membranes were characterized using scanning electron microscopy, atomic force microscopy, porosimeter, attenuated total reflectance Fourier transform infrared spectroscopy, and goniometer. All the prepared membranes were evaluated for BSA separation. The membrane resistance of all membranes decreases with increase in SCER loading. Among all membranes, P3 membrane shows a better fouling, reversible and irreversible resistance for BSA, signifying that the attached BSA on the membrane surface can be easily removed by physical cleaning. The improvement in hydrophilicity of P3 membrane was found to be the dominant factor in mitigating BSA fouling. The results demonstrated that BSA fouling could be alleviated by varying SCER concentration in the polyethersulfone matrix. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45854.

“…Membrane technology has vast applications in various industrial processes, namely in waste treatment [1,2], food and biotechnology industries [3], metal industries [4], textile industries [5][6][7], chemical process industries [8], water production [9] and bacteria/virus removal applications [10]. In general, membranes can be classified based on their morphologies including dense homogenous polymer membranes, porous membranes and thin-film composite membranes [11].…”

This paper addressed the pioneering work on the effects of dual surfactants component on the performance, morphologies and molecular properties of polyvinylidene fluoride/polyether glycol (PVDF/PEG 200) ultrafiltration (UF) membranes. The PVDF surfactant membranes were prepared via dry/wet via phase inversion technique with the addition of sodium dodecyl sulfate (SDS)/Tween 80 and Triton X-100/Tween 80 into polymer solution. Experimental data revealed that the dual surfactants improved the membrane performance up to 120.84 L/m2 × h and 82 % of permeate flux and rejection of bovine serum albumin, respectively. In addition, 2 wt% of dual surfactants alsofound to induce the growth of fine finger-like and macro-voids cavities inside the membranes while the FTIR spectra proved that the existence of dual surfactants in PVDF membranes produced better molecular alignment which contributed significantly towards better flux and good rejection. In conclusion, the used of dual surfactants in the PVDF ultrafiltration membranes improved the performance-properties of the membranes and extending the possibly versatile for the membrane to be used for more applications.

“…Hydrophobic fractions of foulants deposit on the membrane surface and cause irreversible fouling, while the hydrophilic fractions are less likely to accumulate on the membrane surface. Therefore, various techniques have been developed to prevent fouling by enhancing the hydrophilicity of membranes such as coating, blending, plasma treatment, and surface grafting . Blending with hydrophilic polymers, such as PEG and PVP, is one of the most popular approaches, but water‐soluble polymers leach out of the membrane matrix and a small portion of hydrophilic additive remains in the membrane matrix and on the surface …”

A series of polysulfone (PSf)‐based amphiphilic graft copolymers were synthesized to investigate the effects of copolymer composition on membrane morphology and performance. PSf‐based ultrafiltration membranes were prepared by phase inversion method using the blends of PSf and PSf‐g‐poly(ethylene glycol) methyl ether methacrylate (PEGMA) copolymers. Membranes were evaluated in terms of pure water permeability, flux recovery ratio (FRR), protein rejection, and contact angle. The morphology of the membranes was investigated by scanning electron microscopy. Contact angle of membranes was decreased from 85.7° to 51.6°, while the FRR was greatly increased from 55 to 95% upon increasing the PEGMA content of copolymers from 20 to 70 wt %. Results indicated that the ratio of hydrophilic/hydrophobic segments in amphiphilic structures is one the key parameters that control the phase inversion process by altering miscibility, viscosity, and wettability of casting solutions. © 2019 Wiley Periodicals, Inc.
