“…Nevertheless, agglomerations of nanoparticles at high loadings may reduce the void fraction of the membrane. In the literature, different nanoparticles such as carbon nanotubes, zeolites, silica, alumina, Magnesium Oxide, and TiO 2 and SiO 2 are investigated that increase the permeability of the membranes. According to the size of the channels or the interaction between nanoparticles and feed, channeling of the membrane normally leads to decreased selectivity .…”

Removal of aromatic compounds from fuel is an essential requirement in new environmental policies. In the present study, poly(vinyl alcohol)/graphene oxide (GO) mixed matrix membranes were prepared and applied to the separation of toluene from iso‐octane by pervaporation, considering the similarity and interaction between graphene and aromatics. The effects of crosslinking and GO content on separation efficiency have been investigated in detail. Owing to the high affinity of GO with toluene through s and π bonds, the selectivity of the membranes was increased by incorporating a low amount of GO. The results also indicated that noncrosslinked membranes have higher selectivity and permeation flux due to higher crystallinity and also have lower mechanical properties. © 2017 Wiley Periodicals, Inc.

Ultra high molecular weight polyethylene (UHMWPE) filters are widely used in water treatment. In the present work, a facile crosslinking technique is first applied to a UHMWPE flat membrane as a model to realize long‐lasting hydrophilicity and improved water treatment efficiency. In the presence of a crosslinker, N, N′‐methylene bisacrylamide (MBA), 2‐hydroxyethyl methacrylate (HEMA), a hydrophilic modifier, is soaked into the surface of UHMWPE particles by blending. Then, a crosslinking reaction occurs during the initial sintering stage. Finally, sintering is completed at high temperature and pressure. The FTIR and SEM results show that HEMA is successfully crosslinked on the UHMWPE particle surface. Compared to a pristine membrane, the crosslinked UHMWPE flat membrane presents a lower water contact angle and is more rapidly penetrated by water. As a result, the crosslinked membrane can realize pressureless filtration. Another meaningful result is that the water flux recovery rate (FRR) is extremely high both for BSA and sludge filtration tests. Also a parameter K of 1 was obtained to represent the efficiency of the membrane treatment of water under pressureless conditions. These findings demonstrate that the crosslinking strategy is an effective method for realizing long‐lasting hydrophilicity and is very promising for UHMWPE filters and other engineering applications.

Separation by membranes in chemical and allied industries has been of prime importance in the last few decades because of its low energy requirement and environment friendly process. In the last two decades, there has been significant development of this novel separation technology in academic research and industrial applications. Several new membranes such as new kinds of thin film composite membranes, nanocomposite membranes, metal–organic framework membranes, mixed matrix membranes, polyelectrolyte membranes, graphene and carbon nanotube‐based membranes, polymer inclusion membranes, and new kinds of liquid membranes have been developed for applications in reverse osmosis, nanofiltration, ultrafiltration, microfiltration, pervaporation, gas separation or facilitated transport with liquid membranes. Membranes based on functional polymers and composites of polymer and ceramic materials have shown significant improvement in flux, selectivity, or salt rejection. This article discusses elaborately on the basic principles of membrane separation, types of membranes/modules, synthesis, and characterization of new membrane materials with citation of recent works on this novel separation process.
