“…Following Biswas and Bandyopadhyaya all the SPES membranes were impregnated with Ag‐NPs. The respective membrane was placed in a small petri dish with 50 mL, 0.01 mol L ‐1 silver nitrate (AgNO 3, Qualigens, India) solution and kept in a dark environment for 6 h (to prevent oxidation) for attachment of Ag + ions with the sulfonic acid groups present on the membrane.…”

“…To test the anti‐bacterial performance of Ag‐SPES membranes, a lab scale cross‐flow membrane module was used with a membrane area of 4 cm × 9 cm. Details of this membrane module were discussed in an earlier paper . A model bacterial organism Escherichia coli K12 (MTCC 1302, Chandigarh, India) was used for cell‐attachment experiments.…”

“…CLSM images were captured for the same area, after 5 min also. To differentiate live and dead cells two fluorescent dyes namely, SYTO‐9 and propidium iodide (PI) (Life Technologies, Bengaluru, India) were used . SYTO‐9 stains all the cells attached to the membrane surface and PI stains all the dead cells.…”

“…This will lead to pore blockage and subsequent reduction in membrane performance. Therefore the only possible solution would be to use prefabricated membranes directly for surface modification and selective impregnation of Ag‐NPs in the membrane . To the best of our knowledge, no research has been reported on the effect of varying the degree of sulfonation towards Ag‐NP loading and development of rechargeable polyethersulfone (PES) membrane for antibacterial applications.…”

“…Many authors have proposed strategies to produce a hydrophilic membrane from hydrophobic polymers. Among them are blending with hydrophilic additives [9,10], grafting the surface of the membrane with a monomer [11], and copolymerization of several polymeric additives [12]. Hydrophilic PES membranes can also be made by blending the polymer solution with chitosan [13], which can decrease the water contact angle to about 56º (highly hydrophilic properties).…”

Membrane-based processes have become the most dominant technology for water or wastewater treatment. To maintain optimum performance, a membrane should have high permeability and selectivity, good hydrophilicity, in combination with stable mechanical properties. Generally, the membrane produced from pure polyethersulfone (PES) has good mechanical properties, but low hydrophilicity. Modifications of the PES membrane with hydrophilic additives can increase its hydrophilicity. Nevertheless, incorporating additives may decrease its mechanical properties. The objective of this study is to enhance the overall properties of PES membrane by incorporating nanocarbon as an additive. The goal is to obtain a membrane with high permeability and selectivity, good hydrophilicity, as well as superior mechanical properties. Four PES membranes were equipped via the dry-wet inversion method using two solvents (n-methyl-2-pyrrolidone (NMP) and dimethyl sulfoxide (DMSO)). The nanocarbon additive was fabricated from palm fruit-shell biomass wastes. The results show that the type of solvent affects the pore structure of the membrane surface. The membranes prepared using the PES-NMP system have dense structures with small nodules that appear in the upper skin layer, while the membranes from the PES-DMSO system have a spherulite-like structure. The membrane structures changed significantly when the nanocarbon particles were added to the polymer solution, particularly in terms of the shape and size of the microvoids. The finger-like structure found in the membranes prepared from PES-NMP or PES-DMSO systems disappears after the nanocarbon was added to the system. Furthermore, the accretion of nanocarbon to the polymer system increases the water permeability, hydrophilicity, and mechanical properties of the resulted membrane.

Sulfonated polyethersulfone (SPES), polyaniline (PANI), and Cloisite 15 A ® were used as modifiers for the fabrication of Mindel composite polymer electrolyte membranes (PEMs). Pristine Mindel and Mindel composite PEMs were fabricated by the solution intercalation technique. The presence of modifiers in the Mindel membrane matrix was confirmed by Fourier transform infrared (FTIR) studies. The primary characteristics of pristine Mindel and Mindel PEMs such as water uptake, methanol uptake, proton conductivity ion-exchange capacity (IEC), and chemical and mechanical stability were evaluated. The pore size of Mindel/SPES/Cloisite 15 composite PEM was increased owing to the addition of SPES and Cloisite 15. The higher proton conductivity of 4.323 × 10 −4 S cm −1 , enhanced IEC of 0.482 mequiv. g −1 , and maximum water uptake (%) of 38.12 were noted for Mindel/SPES/Cloisite membrane. Membrane selectivity of all Mindel PEMs was enhanced by the addition of modifiers. The results of this study indicate that Mindel composite membranes could be utilized as PEMs for direct methanol fuel cell (DMFC).
