“…Polymeric membranes have won fascinating opportunities because of their low cost, easy processability, and tunable physical and chemical properties. The polymers for desulfurization mainly comprise poly(dimethyl siloxane) (PDMS), poly(ethylene glycol) (PEG), and poly(ether‐ block ‐amide) (Pebax) . However, the broad application of polymeric membranes is severely hampered by the intrinsic trade‐off between permeability and selectivity .…”

Hollow monocrystalline silicalite-1 (HMS) nanoparticles were successfully synthesized and firstly incorporated into poly(etherblock-amide) (Pebax) to prepare hybrid membranes. The uniformly dispersed HMS in Pebax matrix interrupt the crystalline region and optimize the free volume property. The micropores on the HMS shell enhance the selectivity because of sieving effect, whereas the inner cavity benefits the rapid diffusion of penetrant and elevates the flux. When the content of HMS (200 nm) is 20 wt %, the hybrid membrane possesses a permeation flux of 20.63 kg/(m 2 h) and an enrichment factor of 6.11 (82% and 23% higher than that of Pebax membrane, respectively), which surpass the upper bound of the state-of-the-art reported polymeric membranes. Moreover, the hybrid membranes display the remarkable antiswelling and long-term operation stability. This is a step forward in fabricating the hybrid membranes with superior separation performance by incorporating porous fillers with hollow structure.

“…Meanwhile, anomalous phenomena e.g. ultraflux [13][14][15][16] and breaking-tradeoff [17][18][19] have also been observed in nano-confined membrane processes. Therefore, it is necessary to investigate the nano-confined mass-transfer models.…”

How to reduce flow resistance of nano-confined fluids to achieve a high flux is a new challenge for modern chemical engineering applications, such as membrane separation and nanofluidic devices. Traditional models are inapplicable to explain the significant differences in the flow resistance of different liquid-solid systems. On the other hand, friction reduction in liquid nano-lubrication has received considerable attention during the past decades. Both fields are exposed to a common scientific issue regarding friction reduction during liquidsolid relative motion at nanoscale. A promising approach to control the flow resistance of nano-confined fluids is to reference the factors affecting liquid nano-lubrication. In this review, two concepts of the friction coefficient derived from fluid flow and tribology were discussed to reveal their intrinsic relations. Recent progress on low or ultra-low friction coefficients in liquid nano-lubrication was summarized based on two situations. Finally, a new strategy was introduced to study the friction coefficient based on analyzing the intermolecular interactions through an atomic force microscope (AFM), which is a cutting-point to build a new model to study flowresistance at nanoscale.

“…9 In order to improve the PV desulfurization performance, the membrane commonly need to be modified. For example, commonly used modification methods include doping, [10][11][12][13][14] blending, 15,16 crosslinking 17,18 and copolymerization, 19,20 and so forth. Han et al 10 improved the performance of PDMS membranes by incorporating metal organic framework CPO-27-Ni.…”

In this article, the 3-methacryloxypropyltrimethoxy silane (KH570) was deposited onto the surface of the polyurethane (PU) membrane to prepare pervaporation (PV) desulfurization membrane. The modified membrane was characterized by Fourier transform infrared spectrum, scanning electron microscopy, and atomic force microscope and so forth. After modification, the surface exhibited a special morphology with cracks which was microcontrolled by adjusting the hydrolysis time, the concentration and the deposition time of KH570. Through the PV performance of the modified membrane, it was found that the surface morphology with cracks effectively reduced the mass transfer resistance and enlarged contact area, which played a key role in the increase of flux. Under the optimal modification conditions, the flux of the membrane was 2.41 kg m À2 h À1 , which increased by 154% in comparison with the pristine PU membrane, while the enrichment factor maintained a satisfactory level of 7.35. Therefore, this study provided a new insight to fabricate a high performance PV desulfurization membrane.
