Membrane technology is an essential tool for water treatment and biomedical applications. Despite their extensive use in these fields, polymeric-based membranes still face several challenges, including instability, low mechanical strength, and propensity to fouling. The latter point has attracted the attention of numerous teams worldwide developing antifouling materials for membranes and interfaces. A convenient method to prepare antifouling membranes is via physical blending (or simply blending), which is a one-step method that consists of mixing the main matrix polymer and the antifouling material prior to casting and film formation by a phase inversion process. This review focuses on the recent development (past 10 years) of antifouling membranes via this method and uses different phase-inversion processes including liquid-induced phase separation, vapor induced phase separation, and thermally induced phase separation. Antifouling materials used in these recent studies including polymers, metals, ceramics, and carbon-based and porous nanomaterials are also surveyed. Furthermore, the assessment of antifouling properties and performances are extensively summarized. Finally, we conclude this review with a list of technical and scientific challenges that still need to be overcome to improve the functional properties and widen the range of applications of antifouling membranes prepared by blending modification.

“…This has been achieved using benign, bio-based solvents with strong polarity such as γ-valerolactone (GVL), dimethyl isosorbide (DMI) and dihydrolevoglucosenone (Cyrene TM ) 28 . PES dope solutions prepared with γ-valerolactone yielded sponge-like membranes with no macrovoids after NIPS 29 , while replacing NMP with Cyrene TM typically yield membranes with dense structures and hence lower water fluxes after NIPS 30,31 . Alternatively, PES dope solutions prepared with dimethyl isosorbide can produce membranes with pure water permeance of 6300 L•m -2 •h -1 •bar -1 32 .…”

“…Cyrene is more miscible with water than NMP. This leads to slower and non-uniform precipitation across the dope solution film 30 . This could increase surface porosity and surface roughness surface, which was also in line with trends in surface morphologies in Fig.…”

Every year the problem of water purification becomes more relevant. This is due to the continuous increase in the level of pollution of natural water sources, an increase in the population, and sharp climatic changes. The growth in demand for affordable and clean water is not always comparable to the supply that exists in the water treatment market. In addition, the amount of water pollution increases with the increase in production capacity, the purification of which cannot be fully handled by conventional processes. However, the application of novel nanomaterials will enhance the characteristics of water treatment processes which are one of the most important technological problems. In this review, we considered the application of carbon nanomaterials in membrane water purification. Carbon nanofibers, carbon nanotubes, graphite, graphene oxide, and activated carbon were analyzed as promising materials for membranes. The problems associated with the application of carbon nanomaterials in membrane processes and ways to solve them were discussed. Their efficiency, properties, and characteristics as a modifier for membranes were analyzed. The potential directions, opportunities and challenges for application of various carbon nanomaterials were suggested.
