Zusammenfassung der Projektergebnisse
The goal of this project was to meet the growing demand for non-toxic anti-biofouling coatings. Biofouling is one of the fundamental problems that is far from being solved. For decades, marine biofouling has been treated with toxic paints containing Sn or Cu biocides, which have been released into the marine environment, causing damage to the surrounding aquatic environment. Since 2008, some toxic components have been banned by the International Maritime Organization, while others were subjected to the International Convention on the Control of Harmful Anti-Fouling Systems, which was submitted to the EU competent authorities in 2018. Bacterial fouling is another major challenge. It leads to reduced efficiency, increased operating and maintenance costs, and system failures in a variety of industries. It can cause corrosion, mechanical blockages, infections in medical devices, and contamination in food processing, ultimately affecting economic performance and safety. We proposed to develop a non-toxic alternative for anti-biofouling coatings. The research combined multi-stage non-toxic approaches to combat biofilm attachment and growth. During the project, we focused on two different non-toxic anti-biofouling technologies, both based on changes in the surface properties.
