Macromolecular Rapid Communications, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

Abstract Functional fibrous membranes with high mechanical properties are intensively developed for different application fields. In this study, to enhance moisture and air permeability without compromising strength, a facile float‐surface modification strategy is employed fabricate Janus distinct hydrophobicity/hydrophilicity using the high‐density polyethylene (HDPE) membranes. By coating one side of HDPE polydopamine (PDA) superhydrophilic polyelectrolyte, obtained demonstrate an excellent water transmission rate (577.61 ± 72.66 g m − 2 h −1 ), vapor (WVTR, 131.62 24.34 ) gas (17,496 235 3 bar which much better than those commercial (Tyvek 518.93 23.20 , WVTR 53.09 6.19 2,871 145 ). Further, keep outstanding strength (17.00 4.26 MPa tensile 45.49 8.75% strain at break), exhibit asymmetric wettability on each demonstrated by separation experiments various oil‐water mixtures. This simple approach not only improves serviceability but also offers scalable potential apparel applications other industrial applications.

Comparative Analysis of Treatment Effects of Different Materials on Thin Oil Films

Materials, Год журнала: 2025, Номер 18(7), С. 1486 - 1486

Опубликована: Март 26, 2025

With the continuous and rapid development of global industries, issues such as offshore oil spills, leakage organic chemicals, direct discharge industrial oily sewage have caused serious damage to ecological environment water resources. Efficient oil-water separation is widely recognized solution. However, there an urgent need address difficulties in treating thin films on surface low efficiency existing materials. In view this, this study aims investigate high-efficiency materials for films. Four types with different are designed treat surface. The effects factors film thickness, pressure, temperature performance these studied. viscosities kerosene diesel tested, adsorption products solvents examined. addition, long-term stability movable portable components verified. results show that oil-absorbing sponge-based membrane has excellent microporous structure roughness, endowing hydrophobicity lipophilicity, exhibiting good performance. filtration flux increases increase pressure temperature. It solvents. Moreover, it maintains stable operation during 12-month process oil.

Improved Oil/Water Separation by Employing Packed-Bed Filtration of Modified Quartz Particles

Water, Год журнала: 2025, Номер 17(9), С. 1339 - 1339

Опубликована: Апрель 29, 2025

This study explores the development and optimization of quartz-based filtration media for industrial oil–water separation, focusing on enhancing surface wettability, minimizing fouling, improving oil rejection efficiency. High-purity quartz particles (SiO2: 98%, Fe2O3: 0.18%, particle size: 0.8–1.8 mm) were evaluated in three configurations: raw, acid-washed, surface-coated with hydrophilic nanoparticles (Al2O3 P2O5). The medium was constructed as a packed-bed rather than continuous sintered membrane, providing cost-effective modular structure separation processes. Comprehensive material characterization performed using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS). XRD confirmed crystalline stability across all treatments, while SEM EDS revealed enhanced morphology elemental distribution—especially phosphorus aluminum—in coated samples. Performance testing synthetic oily wastewater (initial concentration: 183,754.8 mg/L) demonstrated that achieved superior reducing residual concentration to 29.3 mg/L, compared 1583.7 mg/L 1859.8 washed raw quartz, respectively. Contact angle analysis improved hydrophilicity media, which also exhibited lower fouling propensity. Taguchi (conducted via Minitab 21.3) regression modeling identified coating operational pressure (optimal at 2.5 bar) most significant parameters influencing rejection. Post-filtration structural integrity durability. Additionally, flux recovery above 90% after backwashing indicated strong regeneration capability. These findings validate surface-modified packed beds robust, scalable, economically viable alternatives conventional membranes treatment. Future research will explore multilayer coatings, long term performance under aggressive conditions, AI-based prediction models.
