Polymers Containing Quaternized Nitrogen for Antifouling Coatings
Effective antifouling properties
Antifouling coatings This technology is available for licensing.
Researchers at the University of California, Santa Barbara have developed a polymer that exhibits antifouling properties, including antimicrobial and antialgal properties. This polymer can inhibit or prevent the growth of microbes, such as bacterial colonies and/or algal cells, by effecting cell lysis and death. Specific organisms that can be inhibited include Ulva (green alga), Navicula (diatoms), and Staphylococcus aureus bacterium, among others.

Background Marine fouling is a major problem in the transport of materials by sea as it can raise fuel consumption by as much as 30%. Environmentally friendly coatings that protect the hulls of ships below the waterline against fouling by seaweed, barnacles, and other organisms are currently sought by the shipping industry. Fouling by these organisms produces additional drag on the ship, thereby increasing operating and maintenance costs. There is a need for a material that has antimicrobial properties to reduce marine bio-fouling, thereby decreasing the accumulation and buildup of marine organisms and aiding in their removal. Such a material would preferably lack toxic copper or tin metals, and lower the strength of adhesion between marine fouling organisms and surfaces in contact with a marine environment.
