Buoyancy-Assisted Fabrication of Liquid Diode: Janus Nanofibrous Membrane for Efficient Wastewater Treatment

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(32), С. 42641 - 42659

Опубликована: Авг. 1, 2024

The pressing need for effective methods to separate oil and water in oily wastewater has spurred the development of innovative solutions. This work presents creation evaluation a Janus nanofibrous membrane, also known as Liquid Diode, developed using electrospinning (e-spinning) buoyancy-assisted hydrothermal techniques. membrane features unique structure: one side is composed PVDF nanofibers embedded with GO/TiO2 composite, exhibiting in-air superhydrophobic superoleophilic properties, while reverse consists ZnO nanorod array, demonstrating superhydrophilic underwater (UW) superoleophobic properties. distinct asymmetric wettability enables effectively both water-in-oil (w-in-o) oil-in-water (o-in-w) emulsions, achieving an impressive liquid flux separation efficiency (SEff). achieves maximum (Fo) 3506 ± 250 L m–2 h–1, (Fw) 1837 150 SEff exceeding 98% sides. Furthermore, maintained reliable mechanical stability after 10 cycles sandpaper abrasion test demonstrated excellent chemical when subjected acidic, alkaline, cold hot conditions 24 h. These combined its ability breaking down organic contaminants (98% 2% 210 min) pharmaceutical (97% under visible light, highlight photocatalytic potential. Additionally, membrane's antifouling antibacterial properties suggest long-term sustainable use treatment applications. synergistic combination these superior positions promising solution addressing complex challenges environmental remediation.

Regulation of Oil/Water Separation Using Pyridinium-Based Poly(ionic liquid)s with Prewetted Induced Responsive Transition

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

The development of affordable, intelligent dual-separation technology is crucial for the treatment oil–water mixtures. Pyridinium-based poly(ionic liquid)s (PILs), designed using molecular theory, exhibit unique switching wettability properties, making them ideal use in both aqueous and oily environments. By prewetting material's surface with water or oil, targeted separation these components becomes feasible. PILs are synthesized through cross-linking [Pyr]Cl various cross-linkers auxiliary agents. Studies on wetting mechanism materials have identified bursting pressure structure as key factors influencing their properties. They hydrophilic lipophilic properties air, hydrophobic under oleophobic water, achieving a 99% efficiency. A reusability study demonstrated maintenance 90% efficiency after 10 cycles, highlighting sustained high performance. This research presents promising avenues application PIL-based separation, environmental remediation, industrial processing.
