As a result, the marine industry is facing rigid environmental regulations on the use of coatings with biocide-releasing mechanism.
Under the scope of a previous FCT-funded project, heading by the Pl, nature-inspired antifoulants (NIAFs) were synthesized and some were chemical immobilized in commercial marine coatings. It was observed that NIAFs did not lose their bioactivity after chemical immobilization and therefore they may provide new non-toxic bioactive coatings systems able to prevent hard fouling with minimal release of the bioactive compound into the aquatic environment. These results strongly motivate the PI to further explore these NIAFs as viable option to replace copper. A multidisciplinary team was gathered in this project to synergically act to consolidate, strengthen, and increase the international competitiveness of these potential environmentally benign AF products. To achieve this goal, synthetic procedures will be optimized to significantly reduce the environmental footprint and NIAFs starting materials will be extracted from grape wastes with green methodologies developed by our consultant.
To understand the persistence of NIAFs, and consequently their risk of long-term adverse effects in the ecosystem, half-life determination will be conducted through hydrolysis, photolysis and biodegradation by the new team of Environmental Chemists and Microbiologists, and the main transformation products (TPs) will be identified by liquid chromatography-high resolution mass spectrometry (LC-HRMS)."
