Summary: Blending amphiphilic zwitterion polysulfone-co-sulfobetaine polysulfone copolymer for preparing antifouling polysulfone UF membranes results in membranes with improved surface hydrophilicity and excellent antifouling ability. The blend membranes show increased porosity, water permeance, pure water flux, and flux recovery ratio compared to traditional membranes. They also exhibit high BSA rejection and minimal variance in water flux and rejection after heat treatment, demonstrating excellent thermostability.

Summary: In this study, PEI-SiO2/PSF nanocomposite membranes were prepared using nonsolvent-induced phase separation. The results showed that PEI-SiO2 nanoparticles were uniformly dispersed in the PSF-based membranes, leading to a decrease in water contact angle and improvements in fouling resistance and permeability.

Summary: Breaking the trade-off between filtration performance and antifouling property, this study proposes a novel design route for thin-film nanocomposite nanofiltration membranes, by grafting well-defined zwitterionic copolymers onto polyamide surfaces. The modified membranes exhibit enhanced hydrophilicity, larger surface area, and thinner polyamide layer, resulting in tripled water permeability while maintaining high rejection rate. The modified membrane also demonstrates exceptional antifouling properties in both static and dynamic fouling tests.

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.

Summary: In this study, air plasma and spray technology were used for surface modification by generating hydroxyl groups and spray-coating PS-r-PEGMA copolymers. The best antifouling properties were achieved with PS50-r-PEGMA50, with a coating density of 0.3 mg/cm² significantly reducing biofouling. This surface modification technique effectively reduced biofouling by at least 75% on various materials and greatly increased signal sensitivity on blood-typing well plates.
