All rights reserved. membranes, which can be mainly classified into surface modification, nanoparticle incorporation and blending modification (Fang et al, 2009;Li et al, 2010;Nady et al, 2011). Surface modification is usually achieved by coating or grafting a functional layer on the prepared membrane surface, in which most of the modified sites occurred on the top and/or bottom surface of the membrane, excluding the pores inside the membrane, due to the limited diffusion ability of the modifying agents into the membrane pores (Zou et al, 2011).…”

Biocompatibility of modified polyethersulfone membranes by blending an amphiphilic triblock co-polymer of poly(vinyl pyrrolidone)–b-poly(methyl methacrylate)–b-poly(vinyl pyrrolidone)

“…The results indicated that the antifouling ability of a PES membrane with a silica-PVP nanocomposite additive was better than that of a PES membrane with a PVP additive. To avoid elution acrylonitrile (AN) and methyl methacrylate (MMA) were used to synthesize co-polymers containing vinyl pyrrolidone (VP) chains by free radical solution polymerization in recent studies [28,29]; the co-polymers poly(acrylonitrile-coacrylic acid-co-vinyl pyrrolidone) P(AN-co-AA-co-VP) [28] and poly(methyl methacrylate-co-acrylic acid-co-vinyl pyrrolidone) P(MMA-co-AA-co-VP) [29] were blended with PES to prepare the modified membranes. The terpolymers were water insoluble due to the AN (or MMA) chains.…”

Heparin-like surface modification of polyethersulfone membrane and its biocompatibility

“…SPES containing sulfonic acid groups exhibited good blood compatibility and could be simply prepared by chemical modification method [24,25]. P(AN-AA-VP) could be synthesized by a conventional free radical solution polymerization [26] and be directly blended into PES to modify the membrane. Moreover, the amounts of anionic groups of the sulfonic acid and carboxylic acid groups were changed with varying the ratios of SPES to P(AN-AA-VP), and the synergistic effect of the different amounts of these anionic functional groups on the blood compatibility was studied in detail, which had not been reported.…”
