“…An air plasma treatment was applied to enhance the hydrophilicity of the coating material and increase the water permeability, while there was no change in superoleophobic properties. Wei et al [ 23 ] used maleic anhydride to graft onto a polyacrylonitrile (PAN) membrane surface via ultraviolet irradiation. Hyperbranched polyester grafting onto the PAN membrane surface, by the reaction of hydroxyl groups with anhydride groups of maleic anhydride, followed the grafting process.…”

A facile and low-cost method has been developed for separation of oily wastewater. Polyvinylidene fluoride/polyacrylonitrile (PVDF/PAN) nanofibers laminated on a supporting layer were tested. In order to create highly permeable and fouling-resistant membranes, surface modifications of both fibers were conducted. The results of oily wastewater separation showed that, after low vacuum microwave plasma treatment with Argon (Ar) and chemical modification with sodium hydroxide (NaOH), the membranes had excellent hydrophilicity, due to the formation of active carboxylic groups. However, the membrane performance failed during the cleaning procedures. Titanium dioxide (TiO 2 ) was grafted onto the surface of membranes to give them highly permeable and fouling-resistance properties. The results of the self-cleaning experiment indicated that grafting of TiO 2 on the surface of the membranes after their pre-treatment with Ar plasma and NaOH increased the permeability and the anti-fouling properties. A new surface modification method using a combination of plasma and chemical treatment was introduced.

“…The resulting membrane exhibited good mechanical strength and biocompatibility and demonstrated 45.8% and 82.6% for lysozyme and urea clearance, respectively, and 98.8% BSA retention (Yu et al, 2017). Wei et al (2016) grafted maleic anhydride onto a PAN membrane surface by UV irradiation followed by chemically attaching hyper-branched polyester with anhydride groups of maleic anhydride. The modified membrane showed better antifouling, biocompatibility, and hydrophilic properties than the non-modified membranes (Wei et al, 2016).…”

The modified membrane showed better antifouling, biocompatibility, and hydrophilic properties than the non-modified membranes (Wei et al, 2016). Roy et al (2015) fabricated three different types of membranes with dialysis grade MWCO (6-16 kDa) and examined the hemocompatibility, cytocompatibility, and permeation performance of urea and creatinine solutes.…”
