Abstract

See full text

Durable antibacterial coatings are prepared by inter-diffusing zwitterionic polyurethane in acrylic polyurethane. Bacterial attachment is substantially eliminated from the surface of the coatings due to the hydrophilicity of the zwitterionic polyurethane. Long-term antibacterial properties were observed for both Gram-negative and Gram-positive bacteria even when the coatings were constantly challenged by mechanical abrasion.
