Two-dimensional membrane materials are widely used for accurate screening of oil and water contaminants important purification. In addition, the dyes contained in bodies particle put more demands on membrane’s functionality. this paper, hybridized nanofiber membranes (WPPLT) were prepared from PAN PVDF-HPF, which loaded with LDHs tannic acid (TA) as carriers. The results showed that PVDF-HPF was able to cross-link fiber surface, nano-LDHs TA improved roughness membrane, thus effectively enhancing hydrophilic properties. Meanwhile, WPPLT has good underwater repellency achieves than 99% separation efficiency a variety surfactant-stabilized emulsions. Continuous tests have shown stable flux. approximately 90% mechanical stretch performance relative original electrostatic spinning facilitates use complex environments. Finally, achieve photodegradation methylene blue (MB) (degradation rate >90%). This study provides new insights into preparation nanofibrous purification, prospects their application contaminants.

The synergistic treatment of oily wastewater containing organic hazards and emulsified oils remains a big challenge for membrane separation technology. Herein, the photocatalytic membrane, which combined physical barrier catalytic oxidation-driven degradation functionality, was fabricated via anchoring nanoflower-branched CoAl-LDH@PANI Z-scheme heterojunction onto porous polyacrylonitrile mat using tannic acid as an adhesive. assembly such offered superior performance soluble dyes tetracycline (up to 94.3%) with improved activity 2.33 times compared CoAl-LDH@pPAN membrane. Quenching experiments suggested that •O2– most reactive oxygen species in reaction system composite greatly enhanced attributed effective inhibition photogenerated hole–electron combination PANI carrier, charge transferring from LDH PANI. possible mechanism proposed based on VB-XPS, electron spin resonance spectroscopy, DRS technologies, confirmed by density functional theory calculation. Meanwhile, benefiting superhydrophilic/oleophobic feature low oil adhesion, exhibited high permeability isooctane emulsion (3990.39 L·m–2·h–1), structure stability, satisfactory cycling performance. This work provided strategy develop superwetting membranes treating complex multicomponent pollutants chemical industry.

The efficient separation of oil/water mixtures by membrane technology is highly dependent on the performance materials. emergence electrospinning has opened up opportunities for designing super porous structures with excellent efficiency. Herein, we prepared electrospun nanofibrous membranes using a hydrophilic and thermomechanically stable polyamide-imide (PAI) polymers. fabricated set optimized processes were examined in gravity-driven various emulsions. effect polymer concentration fiber diameter porosity was evaluated. It observed that increasing PAI dope resulted fabrication larger fibers pore size. thus, size influenced flux efficiency during filtration. 12% (EM1) showed lower flux, whereas 21% (EM4) offered higher but exhibited underwater antioil adhesion behavior completely repelling n-hexane, mineral oil, n-hexadecane, gasoline droplets from their prewetted surfaces. Compared to other membranes, 15% (EM2) found strike balance between water oil rejection while also exhibiting strong resistance fouling, as evidenced its relatively decline (FD) recovery ratio (FRR) when filtering EM2 demonstrated an pure 800 900 L/m2 h (LMH) emulsion 380 410 LMH. FRR 91–97 >99%, respectively. Moreover, at pH 3 9 consistent performance. utilized n-hexane/water cyclic tests provided after 10 cycles, demonstrating high potential this real processes.
