Antifouling and antibacterial behavior of membranes containing quaternary ammonium and zwitterionic polymers

Ming-Ming Zhu et al.

Summary: A dual-functional ultrafiltration membrane containing quaternary ammonium and zwitterionic polymers was designed to overcome organic/bio-fouling, with improved hydrophilicity and antibacterial properties. The membrane showed higher flux recovery, lower protein adhesion, and efficient broad-spectrum antibacterial performance against S. aureus and E. coli. It effectively inhibited bacterial adhesion for long-term antibacterial properties, demonstrating potential for microbiologically contaminated water filtration processes.

Selective separation of dye and salt by PES/SPSf tight ultrafiltration membrane: Roles of size sieving and charge effect

Mengyang Hu et al.

Summary: The study developed a Polyethersulphone (PES)/sulfonated polysulphone (SPSf) tight ultrafiltration (TUF) membrane for the selective separation of dyes and salts. The membrane displayed high rejection for charged dyes with similar molecular weight due to the synergy between size sieving and charge effect. The rejection of dyes decreased with increasing ionic strength of feed solutions.

Zwitterionization of Tertiary Amines in Nanoporous Block Copolymers: toward Fouling-Resistant Ultrafiltration Membranes

Chenxu Zhang et al.

Summary: The in situ formation of trimethylamine N-oxide-derived zwitterionic polymers on the surface of nanoporous block copolymers results in ultrafiltration membranes with superior fouling resistance. The oxidation process is fast and achieves high conversion, leading to membranes with enhanced hydrophilicity and tunable permselectivity. These zwitterionized membranes exhibit ultralow protein adsorption and exceptional fouling resistance, outperforming other membranes.
