Constructing Environmental-Friendly “Oil-Diode” Janus Membrane for Oil/Water Separation

ACS Nano, Journal Year: 2022, Volume and Issue: 16(3), P. 4684 - 4692

Published: March 2, 2022

Oil leakage is a global environmental issue and happens frequently, resulting in waste of oil resources even threatening the safety marine creatures humans. Because unidirectional transportation performance, "oil-diode" Janus membranes have attracted lots attention for oil/water separation. However, hydrophobic side traditional membrane completely hydrophobic, an easy permeation oil, which hampers light recycling. Herein, we provide facile approach to develop with special wettable structure fast refining. The material characteristics surface wettability that generate superimposed efforts are vital fabricate membranes. Interestingly, manufactured exhibit extra-high intrusion pressure up 12 kPa present high permeance about 2993 L m-2 h-1 bar-1 separating stable water-in-oil emulsion containing surfactant separation efficiency 99.6%, thereby showing promising potential recovery

Scalable Robust Superamphiphobic Coatings Enabled by Self‐Similar Structure, Protective Micro‐Skeleton, and Adhesive for Practical Anti‐Icing of High‐Voltage Transmission Tower

Advanced Functional Materials, Journal Year: 2022, Volume and Issue: 32(43)

Published: Aug. 17, 2022

Abstract Superamphiphobic coatings have wide application prospects in various fields, but suffer from low mechanical robustness. Although some strategies been reported to solve the issue, it is still challenging for large‐scale preparation of robust superamphiphobic via facile approaches. Here, a universal method mechanically by spraying suspension containing silica nanoparticles decorated with perfluorodecyl polysiloxane and adhesive microparticles on substrates reported. Phase separation avoids embedding forming nanoparticles@microparticles structure meanwhile generates reentrant tri‐tier hierachical micro‐/micro‐/nanostructure. determines micromorphology, chemical composition, superamphiphobicity, robustness coatings. Consequently, show excellent static dynamic superamphiphobicity. Moreover, because combined effects self‐similar structure, protective micro‐skeleton, adhesive. Furthermore, scalable achieved. The can significantly delay water freezing time thus good passive anti‐icing performance 1000 kV high‐voltage transmission tower. It believed that great potential, as simple scalable.

Biodegradable electrospinning superhydrophilic nanofiber membranes for ultrafast oil-water separation

Science Advances, Journal Year: 2023, Volume and Issue: 9(34)

Published: Aug. 23, 2023

Although membrane technology has attracted considerable attention for oily wastewater treatment, the plastic waste generated from discarded membranes presents an immediate challenge achieving eco-friendly separation. We designed on-demand biodegradable superhydrophilic composed of polylactic acid nanofibers in conjunction with polyethylene oxide hydrogels using electrospinning ultrafast purification water. Our results showed that use increased number hydrogen bonds formed between surface and water molecules by 357.6%. This converted hydrophobic into ones, which prevented fouling accelerated emulsion penetration through membranes. The oil-in-water permeance our newly nanofiber 61.9 times (2.1 × 104 liters per square meter hour bar) separation efficiency >99.6%, was superior to state-of-the-art Moreover, formation found accelerate biodegradation lactic over 30%, offering a promising approach treatment.

Bioinspired Superhydrophobic/Superhydrophilic Janus Copper Foam for On-Demand Oil/Water Separation

ACS Applied Materials & Interfaces, Journal Year: 2022, Volume and Issue: 14(9), P. 11981 - 11988

Published: Feb. 28, 2022

Superwettable Janus membranes with unique interfacial characteristics have versatile applications in oil/water separation, microfluid transportation, and membrane distillation. However, it remains a significant challenge to simply fabricate three-dimensional (3D) metallic foams superwettability using facile environment-friendly method. In this study, novel method is present construct copper foam (CF) by combining superhydrophobicity superhydrophilicity into CF. Based on gravity, the water light oil (LO)/water mixture can be transported from superhydrophilic (SHL) side superhydrophobic (SHB) side, while heavy (HO) HO/water/mixture SHB SHL side. Therefore, cylindrical separation devices superior efficiency excellent repeatability achieve on-demand effortlessly. This design fabrication offers avenue for preparation of interface materials practical liquid sensor devices, energy materials, spills.
