The improvement of antibiofouling efficiency of polyethersulfone membrane by functionalization with zwitterionic monomers

Fabrication of nonfouling, bactericidal, and bacteria corpse release multifunctional surface through surface-initiated RAFT polymerization

“…As reported in the literature, the resistance of bacteria adhesion by the p (DMAEMA + -co-MPC) copolymer brush-coated surfaces can be owing to high surface hydrophilicity and low surface energy. 30,51 Moreover, the number of adhered bacteria decreased greatly with the increase of MPC in the brushes, and the bacteria had been partially killed on contact with DMAEMA + constitution. Comparing with the adhesion of S. aureus at the first 15 seconds, it could be concluded that the quantitative differences become larger and larger.…”

Structures and Synthesis of Zwitterionic Polymers

“…In particular, the latter profits from the facile incorporation of reactive groups in special positions, e.g., in the center or at the ends of the polymers, that enable efficient attachment of the macromolecules onto the substrates. Still, classical grafting-from [318][319][320][321][322][323][324][325][326][327][328][329][330][331][332][333][334][335], grafting-to [336][337][338][339][340][341][342][343][344][345][346], and grafting-through [316,347] procedures are of course continuously in use, especially in industrial applications, where the activation of the surfaces for the grafting process by physical means or by simple, "unpretentious" chemistry is preferred for reasons of experience, cost and high-throughput.…”

Preparation of thin-film composite nanofiltration membranes with improved antifouling property and flux using 2,2′-oxybis-ethylamine

“…However, NF technology is greatly limited by membrane contamination from solute, colloidal or organic particles by physical or chemical interactions with membranes [7]. Generally, pore size, the charge density, and the surface hydrophilicity of NF membranes are critical factors for rejection behavior of NF membrane and application fields [8][9][10][11]. However, the pores are small enough and prone to be polluted by microorganism or protein.…”
