Polyphenylene sulfide (PPS) nanofibers have broad application prospects in high temperature dust removal, high temperature oil-water separation, radiation protection, and other fields. PPS nanofibers were prepared by melt differential electrospinning without any other additives, which ensures the excellent properties of PPS fibers. The effects of spinning parameters (spinning voltage, spinning distance, spinning temperature) on the morphology of PPS fibers were systematically studied, and the average diameter of PPS fibers with 1.28 μm was obtained under the optimum conditions (spinning distance of 6 mm, temperature of 310 C and spinning voltage of 35 kV). The effect of spinning voltage on the crystallinity and thermal stability of the fiber was analyzed. Finally, the filtration efficiencies of the commercial dust-proof filter bags and the obtained PPS fibers with the same weight were compared. It was demonstrated that filtration efficiency of the obtained PPS fibers with 186 g/cm 2 reached up to 99.95%. This study aims to provide a new idea for green industrial manufacturing and application of electrospinning PPS nanofibers.

“…Compared to traditional separation methods which involve centrifugation, the use of oil‐absorbing porous materials, and magnetic separation approaches, oil/water separation membranes are attractive as they offer the advantages of high selectivity, simple operation, energy efficiency, and small footprint, as well as cause no pollution . In the last two decades, oleophilic membranes have been successfully fabricated, such as carbon‐silica nanofibrous membranes, vertically aligned multiwalled carbon nanotubes (MWNTs) membranes, biodegradable poly(lactic acid) membranes, polystyrene nanofibrous membranes, polytetrafluoroethylene nanofibrous membranes, polyimide‐based nanofibrous membranes, and polyphenylene sulfide microfiber membranes . However, hydrophobic surfaces can be easily fouled owing to their high affinity toward oils, especially high‐viscosity oils, which results in a decrease of their separation efficiency .…”

Polymer/fluorocarbon surfactant membranes have been reported to display excellent oleophobic/hydrophilic behavior and outstanding oil/water separation properties. In this work, multiwalled carbon nanotubes (MWNTs) enhanced poly(styrene‐alt‐maleic anhydride)/fluorocarbon surfactant (PSMA/MWNTs/FS) membrane filters were prepared by dip‐coating PSMA/MWNTs/FS on stainless steel meshes for efficient oil/water separation. The microstructure, thermal properties, wettability, oil/water separation ability, and recyclability were investigated. The results revealed that the MWNTs are suitably dispersed in the membrane, further increasing the thermal stability, oil/water separation efficiency, and recyclability. The oil/water separation efficiency of the complex membrane filter containing MWNTs was 99% initially and 97% after 20 cycles. This work provides a simple, low‐cost, and environmentally friendly approach for efficient oil/water separation.

“…In recent years, membrane separation technology has received increasing attention because of its high efficiency, favorable selectivity and ease-of-operation. [8][9][10][11][12] In general, conventional polymer membranes are fabricated via the phase inversion method, which inevitably causes a decline in flux and serious membrane fouling. In order to solve these problems, polymeric nanofibrous membranes with high porosity, specific surface area and high separation flux have become promising materials for oil/water separation.…”

BACKGROUND: The large-scale oily wastewater from chemical industries and oil spills causes severe damage to ecosystems and affects human health. To date, plenty of superwetting membranes have been applied for efficient oil/water separation, but they still face many challenges when separating emulsified oily wastewater in harsh chemical conditions. RESULTS: Herein, novel thermally and chemically stable super-hydrophilic/underwater super-oleophobic polymer nanofibrous composite membranes were fabricated by a facile and effective strategy. For this purpose, poly(arylene ether nitrile) (PEN) nanofibrous matting prepared from electrospinning was chosen as a supporting layer, which possessed excellent performance including anticorrosion, high thermal stability and tensile strength. Based on this, polydopamine (PDA) and 3-aminopropyltriethoxysilane (APTES) were easily and uniformly co-deposited onto the porous PEN supporting layer via a one-step immersion process. The resulting PEN composite membranes possessed stable super-hydrophilic/underwater super-oleophobic properties because of strong adhesion, abundant hydrophilic groups and the hierarchical micro-/nanostructure. Consequently, these membranes could separate various surfactant-stabilized emulsions under low driving pressure (0.04 MPa), with high permeation flux (6121 L m −2 h −1) and oil rejection ratio (>99.63%). Furthermore, the PEN nanofibrous membranes exhibited stable super-wetting and long-term separation performance under harsh operating conditions. CONCLUSION: The super-hydrophilic/underwater super-oleophobic PEN membranes fabricated via a facile co-deposition strategy realized high separation efficiency, and excellent stability and antifouling property for emulsified oily wastewater under harsh operating environments, which indicated that they may have promising applications for the treatment of complicated oily wastewaters.
