Abstract

The need for low-cost and effective antifouling solutions drives innovation in the fields of chemistry, materials science, and biology. In this work, guided by the antifouling strategies used by fluorescent corals, a series of fluorescent zinc acrylate polymer coatings containing coumarin units (ZAR-coumarin) was successfully prepared. The ZAR-coumarin coatings demonstrated excellent antifouling properties due to the synergistic action of multiple antifouling mechanisms, including fluorescent antifouling, natural bactericidal activity, and self-polishing surface renewal (due to ester group (-COO-Zn-OOC-) cleavage). Compared with zinc acrylate coatings without coumarin units (ZAR), the introduction of coumarin units significantly improved the inhibition efficiency for both bacteria and algae. In marine environment tests, the ZAR-AMCO-1, ZAR-ADMCO-1, and ZAR-CAMCO-1 coatings containing optimized amounts of different types of coumarin units maintained good antifouling properties over a 160-day field test period. This research presents an innovative approach to creating marine antifouling coatings.

期刊介绍： Biomacromolecules is a leading forum for the dissemination of cutting-edge research at the interface of polymer science and biology. Submissions to Biomacromolecules should contain strong elements of innovation in terms of macromolecular design, synthesis and characterization, or in the application of polymer materials to biology and medicine. Topics covered by Biomacromolecules include, but are not exclusively limited to: sustainable polymers, polymers based on natural and renewable resources, degradable polymers, polymer conjugates, polymeric drugs, polymers in biocatalysis, biomacromolecular assembly, biomimetic polymers, polymer-biomineral hybrids, biomimetic-polymer processing, polymer recycling, bioactive polymer surfaces, original polymer design for biomedical applications such as immunotherapy, drug delivery, gene delivery, antimicrobial applications, diagnostic imaging and biosensing, polymers in tissue engineering and regenerative medicine, polymeric scaffolds and hydrogels for cell culture and delivery.
