“…Different properties can be obtained by tailoring membrane with varying blend composition to obtain desired membrane structure. For this purpose, inorganic nano-materials are used as nanofillers to incorporate into polymer matrices for enhanced membrane performance [82,110,111]. Among these methods, surface grafting and surface coating are commonly used to enhance anti-fouling property and imparting hydrophilic character to membrane.…”

During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract

“…Collection and measuring of permeates was done every 5 min. The water flux was deduced from Equation (1) [ 7 , 21 , 24 , 25 , 26 ]:

where J o (L·M −2 h −1 ) = pure water flux, V (L) = volume of the pure water permeates, A (M 2 ) = membrane effective area, and Δ t (h) = time of permeate collection. Triplicate measurements were obtained on three different membranes and the average taken for each membrane to minimize experimental errors.…”

Engineered nanoparticles are known to boost membrane performance in membrane technology. Hitherto, tunable properties that lead to improved hydrophilicity due to increased surface oxygen functionalities upon oxidation of petrol soot have not been fully exploited in membrane filtration technology. Herein, the integration of oxidized petrol soot nanoparticles (PSN) into polyethersulfone ultrafiltration membranes produced via phase inversion technique for dye removal in wastewater is reported. The nanoparticles, as well as the composite membranes, were characterized with diverse physicochemical methods, particularly TEM, SEM, BET, AFM, contact angle, etc. The effect of varying the ratio of PSN (0.05–1.0 wt %) on the properties of the composite membrane was evaluated. The composite membranes displayed increased hydrophilicity, enhanced pure water flux, and antifouling properties relative to the pristine membrane. For example, the obtained pure water flux increased from 130 L·m−2·h−1 for base membrane to 265 L·m−2·h−1 for the best composite membrane (M4). The best flux recovery ratio (FRR) observed for the membranes containing PSN was ca. 80% in contrast to 49% obtained with the pristine membrane indicative of the positive influence of PSN on membrane antifouling behavior. Furthermore, the PSN composite membranes displayed relatively selective anionic dye rejection of ˃95% for Congo red and between 50–71% for methyl orange compared with 42–96% rejection obtained for cationic methylene blue dye with increasing PSN content. The successful fabrication of polyethersulfone–PSN composite membranes by a simple blending process opens a novel route for the preparation of economical, functional, and scalable water purification membranes capable of addressing the complex issue of water remediation of organic azo dyes.

“…The HMSN‐thin film nanocomposite membranes exhibited enhanced desalination performance with greater hydrophobicity and improved water flux. A HMS/PES composite was synthesized as a membrane with enhanced antifouling properties for ultrafine filtration . Using a 1.5% HMS incorporated HMS/PES hybrid membrane, the pure water flux reached the maximum (195.7 L −1 m 2 h) under 0.1 MPa while the high rejection to BSA (92.6%) as the model foulant still remained ( Figure ).…”

Functionalized hollow nano-and microspheres containing both hollow and mesoporous structures are fascinating materials for a broad range of applications, such as nanoparticle collectors, catalysis, drug delivery systems, immobilization of biomolecules, and the adsorption and separation of gas and pollutants, because of their empty interior. These hollow mesoporous silica materials are synthesized mainly via soft-and hard-templating routes and are usually modified with a range of organic functional groups (SH, NH 2 , CN, CH 3 , CC, benzene, fluorine linked organoalkylsilanes, and ethane-, amine, benzene, and biphenyl-bridged silanes) to improve their performance in many applications. This article outlines the most advanced applications of silica-based and functionalized hollow mesoporous materials that are reported in the last 3 years (January 2014-June 2017). The high applicability of hollow materials in various fields is discussed, including drug delivery and cancer therapy, bioimaging, adsorption/separation, catalysis, thermal and electrical insulators, anticorrosion, sensors, fuel cells, proton conductors, membrane, optics, superhydrophobic surfaces, and fire safety.
