Abstract:

This review introduced the degradation properties of biodegradable polyester plastics in seawater and summarized key seawater⁃degradable polyester materials reported to date. The review further explored variations in the degradation behavior of these polyesters in marine environments and discussed material modification strategies, focusing on polymer types and underlying degradation mechanisms. Finally, considering the current challenges in designing seawater⁃degradable polyesters, the review provided targeted recommendations and insights to guide future research and development in this field.

Key words: seawater environment, polyesters, degradation performance
