Interfacial polymerization allows membranes to have substantially enriched performance for even more advanced water filtration applications. This study presents development and performance evaluation of high-tech, multilayer interfacial composite membranes for advanced water filtration applications. Multilayered membranes comprising polyethersulfone PES (fabric-supported) base, polyamide (PA) permselective layer and polyvinyl alcohol (PVA) protective layer were fabricated using interfacial polymerization techniques. This multilayered membrane was cast on a non-woven polyester support to render mechanical strength and dimensional stability, providing a robust base for membrane casting and coating. Structural analyses revealed enhanced mechanical properties, with tensile strength increasing from 50 to 66 MPa. Contact angle measurements indicated improved hydrophilicity with contact angle reduction from 100.2° to 67.1°. Fabricated membranes demonstrated significant improvements in water flux and salt rejection performance. Results showed pure water flux of 160 L/m²/h for pristine PES membrane cast on non-woven polyester fabric, which decreased to 70 L/m²/h for PES-PA membrane and 65 L/m²/h for PES-PA-PVA membrane at gain of increased permselectivity. Salt rejection was highest for PES-PA-PVA membrane, achieving rejection rates exceeding 96% for Na₂SO₄<b>,</b> 95% for MgSO₄, and 90% for NaCl. Fabricated membranes demonstrated significant improvements in separation performance, achieving dye rejection rates (DRR) of up to 85% for methylene blue and methyl orange, and flux recovery ratios (FRR) ranging from 70 to 85%. Membranes exhibited strong rejection efficiencies of 50–80% for heavy metal ions.

It were studied CMC samples having molecular weights ranging from M_w=90–725 kDa, containing from 40 (γ_carb = 42) up to 120 (γ_carb = 119) carboxymethyl substituents per 100 averaged anhydroglucose units (AGU). 2D NMR spectroscopy confirmed that partial ester substituents formed during the carboxymethylation of cellulose with chloroacetic acid.

The proportion of C6, C2, and C3 substituted units ranges from 1.5:1.2:1.0 to 3.0:2.0:1.0 respectively. The maximum content of oxidized units increases as the degree of carboxymethylation decreases. Periodate oxidation produces DACMC, containing from 8 to 30 oxidized units per 100 averaged AGU. Unsubstituted AGU are oxidized first, while rings substituted at positions 2 and 3 do not react. The oxidized units form seven-membered hemiacetal cycles and do not contain free aldehyde groups.

This study evaluates the rheological, mechanical, morphological, and swelling resistance properties of the composites, incorporating filler contents ranging from 0 to 10 phr (parts per hundred rubber). Rheometric analysis shows that as the filler content increases, there is a corresponding rise in minimum torque, maximum torque, delta torque, and cure rate index, along with a decrease in scorch time and optimum cure time. A higher filler concentration leads to increased compound viscosity, crosslink density, abrasion resistance, and vulcanizate hardness, along with improvements in compression set and swelling resistance. Tensile strength peaks at 6 phr before declining at higher filler levels. Among the modified fillers, A-HNTs exhibit the most notable enhancements in curing behavior, mechanical properties, abrasion resistance, and swelling resistance. Composites containing A-HNTs show a 167% increase in tensile strength, a 67% improvement in stress at 100% elongation, and a 78% boost in tear strength.

This study developed ALLAs using a monomer-limited seeded semi-continuous emulsion polymerization, employing butyl acrylate (BA), methyl methacrylate (MMA), and HEA. The incorporation of HEA significantly improved the stability of latex, as well as the properties of resulting film and its adhesion strength. Furthermore, the findings of FTIR analysis confirmed the successful integration of HEA into the polymer backbone. The average latex particle size remained stable, but particle size distribution widened as HEA concentration increased from 0 to 0.5 wt%. Higher HEA content led to an increase in gel content, glass transition temperature (Tg), and molecular weights (Mn, Mw). Meanwhile, the water contact angle decreased, indicating improved hydrophilicity. The highest peel strength of 5.67 N/15 mm was observed at 0.3 wt% of HEA.

Remarkably, the employed wear mechanisms were observed from field emission scanning electron microscopy, whereas the executed chemical bonds and crystallographic nature were assessed through Fourier transform infrared spectroscopy and X-ray diffraction. The outcome underscores that the minimal concentration of GO (0.5 wt%) and HA (10 wt%) reinforced PEEK composites (HC1) show outstanding tribological properties due to their sound interfacial interaction and strong carbon-carbon bond between GO and PEEK matrix.
