This research interrogates the effect of loading phenolic resin (\({C}_{8}{H}_{6}{O}_{2}\)) and graphene oxide (GO) solutions into a polyethersulphone (PES) matrix to improve the physio-mechanical properties of PES. A new class of thin-film was successfully synthesized by incorporation of phenolic resin (\({C}_{8}{H}_{6}{O}_{2}\)) and graphene oxide (GO) solutions into a 2 wt% polyethersulphone (PES) matrix and its application in pharma packaging was investigated. To alter the mechanical properties of the thin films, a mixture of phenolic resin and graphene oxide was dispersed into a prepared polyethersulphone solution at varying concentrations using a solution mixing technique. the XRD spectra for PES/GO/PR thin films to confirm the presence of GO. The sharp peak was observed at 2θ = 19.79˚. The tensile testing of the polyethersulphone composite thin films revealed an increase in the tensile strength, which rose from 3.74 to 33.91 MPa, and Young's modulus was also improved from 9.97 to 20.85 MPa. Additionally, there was a significant improvement in the percentage elongation, which rose from 1.02 to 1.66% for PC-4, indicating a strong agreement between the filler used and the composition method.

“…This phenomena might be explained by a rise in the amount of water molecules accessing molecular space within membrane matrix due to a boost in ionic conductivity with temperature 53 . PES is a hydrophobic polymer and does not have a very high WU c 54,55 . According to literature studies, it is seen that the WU c of pure PES membrane is approximately 10% or lower 31,56,57 .…”

In this study, the preparation, characterization, and fuel cell performance tests of high‐performance and low‐cost zirconium phosphate (ZrP)‐additive sulfonated polyethersulfone (sPES) membranes, which may serve as a substitute for the commercial membrane used in proton exchange membrane fuel cell (PEMFC), were carried out. ZrP‐additive sPES membranes were prepared by solution casting method with different weight ratios (2.5%, 5%, and 9%). Fourier transform infrared (FTIR), water uptake capacity (WUc), dynamic mechanical analysis, ion exchange capacity (IEx), degree of hydration, impedance analysis, and oxidative stability were used to characterize the created membranes. Ultimately, single‐cell performance experiments were used to evaluate the membranes' performance in real fuel cell environments. ZrP additive improved the WUc, mechanical properties, IEx, and proton conductivity properties of the membrane. WUc of the membranes enhanced by approximately 94% at 80°C, while the proton conductivity augment by approximately 47% with 9% ZrP by weight. 0.97 meq g−1 IEx was obtained for the sPES, whereas it was obtained as 1.41 meq g−1 for sPES‐9ZrP. Oxidative stability experiments for 120‐h determined that all synthesized membranes had a stable structure, and their weight losses varied between 68% and 85%. The sPES‐9ZrP exhibited very high values at 0.6 V, resulting in a power density of 680 mW cm−2 and a current density of 1100 mA cm−2. The results obtained are quite promising, and sPES and ZrP in composite membrane structures have high synergy.

“…For the ST3 membrane, the maximum observed Jw value was 149 LMH in PRO mode and 136 LMH in FO mode. With the addition of TNTs, the trend of rising J w closely matches the rising hydrophilicity [ 69 ]. This difference between the PRO and FO modes of the process’s water flux (J w ) is caused by the way in which the membrane’s structural resistance is applied to the sides of the solutions that it supports [ 70 ].…”

Water treatment is regarded as one of the essential elements of sustainability. To lower the cost of treatment, the wastewater volume is reduced via the osmotic process. Here, mixed-matrix woven forward osmosis (MMWFO) PES membranes modified by a TiO2/Na2Ti3O7 (TNT) nanocomposite were fabricated for treating water from different sources. Various techniques were used to characterize the TNT nanocomposite. The crystal structure of TNT is a mix of monoclinic Na2Ti3O7 and anorthic TiO2 with a preferred orientation of (2−11). The SEM image shows that the surface morphology of the TNT nanocomposite is a forked nano-fur with varying sizes regularly distributed throughout the sample. The impact of TNT wt.% on membrane surface morphologies, functional groups, hydrophilicity, and performance was investigated. Additionally, using distilled water (DW) as the feed solution (FS), the effects of various NaCl concentrations, draw solutions, and membrane orientations on the performance of the mixed-matrix membranes were tested. Different water samples obtained from various sources were treated as the FS using the optimized PES/TNT (0.01 wt.%) MMWFO membrane. Using textile effluent as the FS, the impact of various NaCl DS concentrations on the permeated water volume was investigated. The results show that the MMWFO membrane generated with the TNT nanocomposite at a 0.01 wt.% ratio performed better in FO mode. After 30 min of use with 1 M NaCl and various sources of water as the FS, the optimized MMWFO membrane provided a steady water flow and exhibited antifouling behavior. DW performed better than other water types whenever it was used owing to its greater flow (136 LMH) and volume reduction (52%). Tap water (TW), textile industrial wastewater (TIWW), gray water (GW), and municipal wastewater (MW) showed volume reductions of 41%, 34%, 33%, and 31.9%, respectively. Additionally, when utilizing NaCl as the DS and TIWW as the FS, 1 M NaCl resulted in more permeated water than 0.25 M and 0.5 M, yet a higher volume reduction of 41% was obtained.
