“…Surface hydrophilicity is among the important indicators for hemodialysis membrane as the interaction between membrane surface and biomolecules depends highly on it . At early polymer precipitation process, hydrophilic Fe 2 O 3 NPs migrated spontaneously to the membrane/water interface to reduce their interfacial energy .…”

Middle molecule uremic toxins constitute to a quarter of uremic toxins present in human blood. In a condition where these uremic toxins accumulate in bloodstream due to renal failure, blood purification process using a high performance membrane is required. Here, we develop biocompatible mixed matrix membranes (MMMs) made up of polysulfone (PSf) and iron oxide nanoparticles (Fe2O3 NPs) with the focus to remove middle molecule uremic toxin effectively. The MMMs were evaluated in terms of their biocompatibility and separation performance. At higher Fe2O3 NPs loading, the MMM displayed a huge reduction of protein adsorption and platelet adhesion while maintaining normal blood coagulation time and acceptable complement activation. The optimized MMM exhibited high permeability (110.47 L m−2 h−1 bar−1), protein retention (99.9%) and demonstrated excellent clearance of urea (82%) and lysozyme (46.7%). The PSf/Fe2O3 MMM is proven to have promising attributes for hemodialysis application. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48234.

“…The electronegativity of sulfur is stronger than that of phosphorus; hence, hydrogen bond also exists between the sulfonate group of PSPE and dopamine theoretically. Besides, cation–π interaction can take place between the π system in dopamine (e.g., phenol) and cations in zwitterions [e.g., ─N(CH 3 ) 3 + ], and in aqueous solutions, the strength of cation–π interaction force (the monopole–quadrupole interactions) is greater than that of electrostatic interaction force (the monopole–monopole interactions) because of their low desolvation penalty . These noncovalent interactions between PSPE and dopamine can pull down the noncovalent interactions between PDA aggregations such as hydrogen bond and π–π staking, and reduce the self‐polymerization rate of dopamine furthermore .…”

“…Reverse osmosis (RO) membrane separation technology has been developed into the mainstream essential desalination method owing to its unsurpassed virtue, such as low energy consumption, easy scale‐up, high salt retention, water flux, and wide operating temperature range . However, commercial polyamide (PA) RO membranes tend to be contaminated naturally by various foulants in feed solution due to their insufficient hydrophilicity and high roughness of the surface during the separation process .…”

“…However, commercial polyamide (PA) RO membranes tend to be contaminated naturally by various foulants in feed solution due to their insufficient hydrophilicity and high roughness of the surface during the separation process . As a result, the performance and life span of the membranes are greatly damaged, and then the operating cost increases . Research studies aiming at solving this Achilles' heel have been widely reported all over the world.…”

“…Deposition of dopamine on PA membranes directly does enhance the antifouling performance of the membranes, but the water flux of the membranes will significantly decrease due to the increasing thickness and the dopamine aggregations caused by the self‐polymerization of dopamine . In several cases, dopamine was deposited on the surface acting as a medium; then, the zwitterionic polymers were grafted on the surface via Schiff base reaction, Michael addition reaction, or radical polymerization . Nevertheless, it is still far from the facile and efficient method we desire.…”

Aiming at preparing high‐performance polyamide (PA) reverse osmosis (RO) membrane in a facile and high effective way, the codeposition strategy of dopamine and zwitterionic polymer was first applied to modify PA RO membrane. The noncovalent bonds between dopamine and Poly [2‐(Methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl)ammonium hydroxide (PSPE) act to fix PSPE onto the membrane surface and simultaneously destroy the interaction force between dopamine aggregations so that the modified layer could equably form on the PA layer. PSPE significantly improved the hydrophilicity [the water contact angle (WCA) of S‐D‐3 is 25.3°] of the modified membrane. And, the smoother surface was noticed on the modified membrane. All of these endow the PSPE/dopamine modified membrane superb water flux (the maximum water flux is 51.86 L m−1 h−1 at 1.6 MPa and 25 °C) and impressive antifouling and anti‐adhesion properties to bovine serum albumin (BSA) (protein), sodium dodecyl sulfate (anionic surfactant), and dodecyl trimethyl ammonium bromide (cationic surfactant) with salt retention was well maintained. Notably, in the BSA fouling test, nearly 100% of the flux recovery ratio was achieved. This method is promising to be employed in industrial scale‐up production. © 2019 Wiley Periodicals, Inc. J.

Membrane-based processes such as water purification and harvesting of osmotic power deriving from the difference in salinity between seawater and freshwater, are two strategic research fields holding great promises for overcoming critical global issues like the world growing energy demand, the climate change and the access to clean water. Ultrathin membranes based on two-dimensional materials (2DMs) are particularly suitable for highly selective separation of ions and effective generation of blue energy, because of their unique physicochemical properties and novel transport mechanisms occurring at the nano-and sub-nanometer length scale. However, due to the relatively high costs of fabrication compared to traditional porous membrane materials, their technological transfer towards large-scale applications still remains a great challenge. Herein, we present an overview of the current state-of-the-art in the development of ultrathin membranes based on 2DMs for osmotic power generation and water purification. We discuss several synthetic routes to produce atomically-thin membranes with controlled porosity and we describe in detail their performances, with a particular emphasis on pressure retarded osmosis and reversed electrodialysis methods. In the last section, outlooks and current limitations as well as viable future developments in the field of 2DMs membranes are provided.3
