Although separation of solutes from organic solutions is considered a challenging process, it is inevitable in various chemical, petrochemical and pharmaceutical industries. OSN membranes are the heart of OSN technology that are widely utilized to separate various solutes and contaminants from organic solvents, which is now considered an emerging field. Hence, numerous studies have been attracted to this field to manufacture novel membranes with outstanding properties. Thin‐film composite (TFC) and nanocomposite (TFN) membranes are two different classes of membranes that have been recently utilized for this purpose. TFC and TFN membranes are made up of similar layers, and the difference is the use of various nanoparticles in TFN membranes, which are classified into two types of porous and nonporous ones, for enhancing the permeate flux. This study aims to review recent advances in TFC and TFN membranes fabricated for organic solvent nanofiltration (OSN) applications. Here, we will first study the materials used to fabricate the support layer, not only the membranes which are not stable in organic solvents and require to be cross‐linked, but also those which are inherently stable in harsh media and do not need any cross‐linking step, and all of their advantages and disadvantages. Then, we will study the effects of fabricating different interlayers on the performance of the membranes, and the mechanisms of introducing an interlayer in the regulation of the PA structure. At the final step, we will study the type of monomers utilized for the fabrication of the active layer, the effect of surfactants in reducing the tension between the monomers and the membrane surface, and the type of nanoparticles used in the active layer of TFN membranes and their effects in enhancing the membrane separation performance.

“…On the other hand, during the melt extrusion processing, the structure and properties of the microporous membranes can be determined by the processing parameters include temperature, cooling rate, draw ratio, etc. [ 29–31 ] Hence, it is particularly important to control these parameters. Especially the draw ratio, which is generally considered as one of the most essential parameters to control the crystal structure of films.…”

The nanocomposite microporous membrane of ultra-high molecular weight polyethylene (UHMWPE) and nano-titanium dioxide (nano-TiO 2 ) system was prepared by combining the thermally induced phase separation (TIPS) technique with the extrusion-casting process using liquid paraffin (LP) as the diluent. The effects of variations of TiO 2 content and melt draw ratio on the properties of composite microporous membranes were studied and the optimal processing parameters were further investigated. ATR-FTIR demonstrated that nanocomposite microporous membranes were successfully prepared. The crystallization behavior and morphological evolution of membranes were systematically investigated by WAXD, 2D-SAXS, and SEM. It was found that the stretch-induced orientation of UHMWPE was promoted and the shish-kebab structure was formed for the reason of addition of TiO 2 . The mechanism of combined effects of nanoparticles and stretch-induced orientation on the crystallization behavior of UHMWPE was further discussed and explained. Compared to pure UHMWPE film, the permeability of the optimum performance film was significantly improved, with porosity of 49% and pure water flux of about 193 L m À2 h À1 . Mechanical studies showed that nanoparticles and DR have significant effects on tensile strength and elongation at break. In addition, the thermal stability of composite microporous membranes was found to be improved with the increase of TiO 2 content and melt draw ratio. Thus, this investigation delivers inspiration for the expansion of excellent performance microporous membranes used for battery separators and filtration devices.
