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.

Broad application opportunities exist for photocatalytic degradation and membrane separation technologies in purification of complex multi-component pollutants. Herein, the membrane, which combines physical barrier catalytic oxidation driven functionality, were fabricated via anchoring CoAl-LDH@PANI Z-scheme heterojunction onto porous polyacrylonitrile mat tannic acid as adhesive. The 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- was most reactive oxygen species reaction system composite greatly enhanced activities attributed effective inhibition photogenerated hole-electron combination using PANI carrier, charge transferring from LDH PANI. possible mechanism proposed based on VB-XPS, ESR, DRS technologies, confirmed by density functional theory (DFT) calculation. Meanwhile, benefiting superhydrophilic/oleophobic feature low oil adhesion, fibrous exhibited high permeability isooctane emulsion (3990.39 L·m-2·h-1), while ensuring structure stability satisfactory cycling performance. This work provided a new strategy develop super-wetting membranes treating pollutants petro-chemical industry.
