This technology relates to the synthetic pathway for non-toxic, water-soluble antifouling compounds capable of preserving underwater surface integrity.
The compounds developed are environmentally friendly solutions that meet the needs of the market. The agents inspired by natural products are less toxic and economical. The compound's effectiveness has already been proven in the laboratory on commercial marine paints and are more effective than one of the newer biocides. A proof-of-concept in ocean (30 weeks) allowed to obtain promising results compared to a 30% copper formulation.
This technology provides a nature-inspired and eco-friendly solution to the underwater adhesion of certain organisms (marine bacteria and mussel larvae) on surfaces known as biofouling, which causes deterioration, systems clogging in boats and contamination. This undesired phenomenon stands as a severe issue to numerous industrial sectors due to costly high maintenance and increased fuel consumption. Also, it contributes to the emission of more greenhouse gases, due to an increase in the ship’s weight caused by the organism-augmented drag friction. Besides, the currently used anti-adhesion techniques imply toxic biocides that cause an even greater environmental burden to marine life. These compounds are compatible with commercial marine coatings, which ease the commercial availability of this underwater surface-protecting agent.
