摘要

Marine biofouling has caused huge economic and energy losses, and the application of marine antifouling coatings is one of the effective solutions to this problem. Sily-acrylate based self-polishing coatings are favored because of excellent antifouling performance. However, weak static antifouling performance restricts the development of sily-acrylate based antifouling coatings. To solve this problem, an eugenol ester-based sily-acrylate polymer (EMSPs) is synthesised, which showed both self-polishing and antifouling performance. The highest content of eugenol (EMSP-16) inhibits Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) up to 62.2% and 76.3%, respectively, and inhibits the adhesion of Halamphora sp. and Nitzschia closterium (N. closterium) up to 85.1% and 90.8%, respectively. Mussel adhesion experiments show that mussels tend to avoid coatings with high eugenol content. The eugenol ester-based sily-acrylate polymer provides a new way to develop new environmentally friendly marine antifouling coatings and alleviate heavy metal pollution in the marine environment.
