Abstract
Bacterial adhesion and the subsequent formation of biofilms and biofouling have significant economic and health impacts across all sectors. They are especially impactful in industrial corrosion, healthcare, food processing, agriculture, and waste and drinking water. Synthetic polymers that resist bacterial adhesion are adaptable to a wide range of applications in all of these fields. While there are many bacteria-resistant polymers, some of the best performing include polyethylene glycol (PEG), poly(oxazoline) (POZ), and zwitterionic polymers, with zwitterionic polymers showing the most promise with reductions in bacteria adhesion up to 99% over controls. This review summarizes the demonstrated bacterial resistance performance of these polymer coatings based on literature published over the last ten years. It also identifies the front runners for preventing bacterial adhesion while providing the critical next steps for widespread adoption of this technology.
