“…49 In the second study published in 2021, high-flux composite styrene-acrylonitrile (SAN)/PAN MD membranes were prepared by high-productive electro-blowing and air-assisted electro-spraying techniques. 50 The thickness of the upper layer of the dual-layer nanofiber membrane was controlled to be tiny for balancing the heat and mass transfer resistance and improve permeability. In this regard, the electro-blowing procedure was used to create the nanofibrous PAN layer as the substrate for the SAN nanofibers.…”

Polyacrylonitrile (PAN) is a hydrophilic polymer with good chemical resistance, low price, and excellent processability for fabricating membranes, especially for electrospun nanofiber-based membranes. In this review, the recent developments in the application and modification of PAN membranes are discussed, focusing on some applications such as pervaporation (PV), ion exchange, hemodialysis, membrane distillation, adsorption membrane, and water and wastewater treatment. First, the physicochemical characteristics and the synthesis techniques of the PAN are discussed, and next, the PAN application in the fabrication of membrane is reviewed. Different PAN membranes with their fabrication techniques are reviewed with detailed studies focused on the modification methods. By using different modifiers especially nanomaterial blending, the physicochemical properties and performance (membrane structure, permeability, mechanical strength, hydrophilicity, porosity, and surface charge) of the PAN membranes are improved. Finally, the challenges and future perspective of these membranes are discussed. The review of research progress in this paper may provide an insight into the development of high-performance PAN membranes and spread the applications of PAN membranes in different separation processes in the future.

Superhydrophobic surface is an enabling technology in numerous emerging and practical applications such as self-cleaning, anticorrosion, antifouling, anti-icing coatings, and oil–water separation. Here, we report a facile air-assisted electrospray approach to achieve a superhydrophobic surface by systematically studying spray conditions and the chemistry of a coating precursor solution consisting of silicon dioxide nanoparticles, polyacrylonitrile, and N,N-dimethylformamide. The wettability behavior of the surface was analyzed with contact angle measurement and correlated with surface structures. The superhydrophobic coating exhibits remarkable water and oil repellent characteristics, as well as good robustness against abrasion and harsh chemical conditions. This air-assisted electrospray technique has shown great control over the coating process and properties and thus can be potentially used for various advanced industrial applications for self-cleaning and anticorrosion surfaces.

“…The most popular polymer is polysulfone (PSF) 16 or polyethersulfone(PES) 17 due to their biological stability, especially when compared to environmentally friendlier polymers such as cellulose acetate (CA) or polyacrylonitrile (PAN) which have some drawbacks, for example they require wet storage-long preservation regime. 18 It is well known that the efficiency of interfacial polymerization is highly affected by the porous structure of polymeric substrate with its hydrophilicity. 16 This blended polymeric substrate will be studied in this work to show the effect of using porous polyacrylonitrile (PAN) with polysulfone (PSF) as the main polymeric substrate.…”

In this work, polyamide (PA) layer of (TFC) thin-film composite in reverse osmosis (RO) membranes are compared to facile cost-effective lower rejection RO-blend membranes using graphene oxide. Polyvinyl alcohol (PVA) is crosslinked with glutaraldehyde hydrogel and thereby showing the effect of a fixed concentration of graphene oxide (GO) at different surface modification stages. Surface grafting using methacrylic acid is performed to govern the role of the protective layer on the efficiency of the covered TFC layer as membranes performance regarding salt rejection and permeability. GO concentration of 0.25 wt% in PVA solution shows a maximum % rejection reaching 70 for 3PG and the highest permeate flux for 1PG is 45.52 LMH. While the TFC membranes T and TG have shown higher rejection percentages to reach 88.31% for 3TG of and the highest permeate flux is 30.7 LMH for 1TG and decreases to reach 24.56 LMH for 3TG. Different membrane characterizations are fulfilled through surface morphology, wettability, BET area, and adsorptive fouling.Optimized ratios for tannic acid, ZnO-nanostructure, and graphene oxide with the mixed polymeric substrate are reached. The effect of graphene oxide in the surface grafting layer over blend and TFC membranes are presented.
