Research Progress and Prospect of Marine Antifouling Coatings

Xincheng Yu, Jin Wang, Mingzhe Kou, Zongyi Shi, Yingshui Yu


Marine biological pollution refers to activities such as a large number of barnacles, algae and other organisms or microorganisms gathering and damaging ships or other marine industries. Among them, the most effective way is to use degradable materials as the substrate and add antifouling agents that can destroy fouling organisms. Traditional marine antifouling coatings release toxic substances with broad spectrum, such as cuprous oxide and organotin, so as to achieve effective antifouling. However, with the adverse effects on the marine environment, it is a long way to go to study and prepare environment-friendly antifouling agents. This paper mainly introduces the traditional degradable materials PCL, PLA, etc., and also introduces the current low-toxic antifouling agent DCOIT composite materials and new natural antifouling agents, etc.
