Scalable inter-diffused zwitterionic polyurethanes for durable antibacterial coatings
A novel antibacterial zwitterionic polyurethane developed to form inter-diffused coating films with commercialized acrylic polyurethanes. The antibacterial property is due to the hydrophilic zwitterionic polyurethane. Long-term use for both Gram-negative and Gram-positive bacteria is highly effective even when the coatings were constantly changed by mechanical abrasion.
