Antimicrobial Polymers and Coatings


Microorganisms have strong abilities to survive on the surfaces of ordinary materials; some species of microorganisms, including drug-resistant strains, can stay alive for more than 90 days. Contaminated materials may serve as significant and important sources for cross-contamination and cross-infection. One of the potential methods to reduce such risks is to introduce antimicrobial properties into materials that are frequently touched and thus potentially have a high risk of spreading disease.


In some cases, a desire to control surface microbial contamination in residential, commercial, institutional, industrial, and hygienic applications has resulted in the development of biocidal polymers. These biocidal polymers are attractive candidates for medical devices, hospital and dental equipment, water purification, food storage and transportation, as well as a broad range of related industrial, environmental, hygienic, and bio-protective applications. These polymers can be mixed into other materials like paints and can be used to coat existing devices and structures. While antimicrobial paints and other antimicrobial polymers are commercially available, none of them are believed to provide broad-spectrum function against bacteria, mold, fungi, and viruses simultaneously. This USD technology can provide this desired broad spectrum protection, and the antimicrobial properties are renewable upon a quick bleaching of the painted surface.
