Abstract

Due to the increasingly serious harm caused by marine fouling to humans, marine antifouling has become an urgent issue in the development of marine resources. Many antifouling countermeasures have been explored, among which applying antifouling coatings is the most economical and effective method and is currently the most widely used approach. Given the significant harm of traditional marine antifouling coatings to the ecological environment, focusing on green, efficient and environment-friendly marine antifouling coatings, the development status and research progress of modified polyurethane in marine antifouling were summarized. Polyurethane coatings are divided into solvent-based and water-based types, both of which exhibit good properties such as solvent resistance. Water-based polyurethane coatings are more environmentally friendly, while solvent-based polyurethane coatings have superior water resistance. These coatings can serve as substrate resins in the field of marine antifouling, helping to reduce biological pollution on the surface of marine structures. By modifying polyurethane coating, its antifouling performance can be further enhanced. In this paper, the application of modified polyurethane in marine antifouling coatings was reviewed, and the existing problems and improvement schemes were analyzed to provide references and suggestions for the research and development of marine antifouling coatings.
