Durable CNTs Reinforced Porous Electrospun Superhydrophobic Membrane for Efficient Gravity Driven Oil/Water Separation

Polyurethane/multi‐walled carbon nanotube electrospun composite membrane for oil/water separation

“…The effect of pH is one of the criteria to evaluate the chemical stability of the electrospun membrane in oil/water separation. 59 As seen in Figure 13a, the electrospun composite membrane could tolerate different pH. There was no considerable variation in hydrophobicity while treating with acid or base.…”

A facile and effective strategy to develop a super-hydrophobic/super-oleophilic fiberglass filter membrane for efficient micron-scale water-in-oil emulsion separation

“… 1,2 Therefore, oil/water separation has received widespread attention from academia and industry. 3 Various methods are developed to treat oily wastewater, including centrifugation, 4 absorption, 5 biological treatment, 6 electro-coagulation 7 and gravity separation. 8 However, the application of these traditional methods is greatly restricted due to their low separation efficiency, poor recyclability, high operational cost, etc.…”

“… 22 Wang et al has prepared a porous electro-spun superhydrophobic membrane for efficient oil/water separation. 4 The membrane shows superior ability to separate water-in-oil emulsion. However, it is difficult to reduce the diameter of the electrospinning due to the electrostatic spinning process being affected by too many factors, such as voltage, current and spinning distance.…”

Multifunctional Switchable Nanocoated Membranes for Efficient Integrated Purification of Oil/Water Emulsions

“…PVP removal by washing and the growth of hybrid ZIF-8@ZnO nanorods (to convert PVP/PVDF to ZIF-8@ZnO-PPVDF) significantly increased the BET surface area of the membrane (i.e., from 1.85 to 248.29 m 2 g -1 , Figure S11). 7 The value was much higher than previously reported electrospun fiber membranes (12.5 to 117.2 m 2 g -1 ) likely due to pore generation. S1.…”

“…As shown in Figures S9c & d, a weak adsorption edge appeared in the PPVDF membrane adsorption curve, which indicates its poor visible photoactivity. For the ZnO-PPVDF membrane, an intense absorbance peak located around 300-380 nm and a little increase of the light absorption over the whole visible light region could be observed, which can be attributed to the strong UV absorption properties of ZnO, 7 the formation of conjugated structures and the color of PPVDF membrane changed from white into brownish red. With the formation of hybrid ZIF-8@ZnO nanorods, an obvious increase of the light absorption over the whole light region could be observed, which can be attributed to the formation of conjugated structures.…”
