Zwitterionic sulfobetaine polymers with catechol chain ends were used to coat various hydrophobic polymer sheets, fibers, and a hydrophilic silica surface to reduce fouling.
The study explored how salt concentration affects the quality of these coatings due to the anti-polyelectrolyte properties of sulfobetaine polymers.
The coating method is environmentally friendly, utilizing only water-based solutions and showing effectiveness across several common polymer surfaces like polypropylene and nylon.
