Dynamic Surface Antifouling Materials
Summary
This study proposes dynamic surface antifouling materials that continuously change their surface properties to prevent marine organisms from colonizing underwater structures. This approach could reduce the need for toxic chemical antifouling coatings on ships and marine infrastructure.
The colonization of marine microorganisms, animals and plants on underwater surface forms marine biofouling. It has profound ef-fects on marine industries. To solve the problem, we proposed a strategy of Dynamic Surface Antifouling (DSAF), i.e., continuously changing surfaces can effectively inhibit biofouling organisms landing and adhering, and developed degradable polymer based ma-rine antifouling material. The degradation of polymer chain enables the surface dynamic or self-renewing even on static conditions. The final degradation products of these polymers are low molecular weight molecules, and do not produce marine microplastics. Meanwhile, the degradable polymers act as carriers and controlled release systems for antifoulants, further improving the antifoul-ing efficiency. This article reviews the development of dynamic surface antifouling materials.

Inside Back Cover
This journal back cover describes a dynamic surface antifouling material that prevents marine organisms from attaching by continuously renewing its surface through polymer degradation. The degradation process produces small, harmless molecules rather than microplastics, making the material more environmentally friendly than conventional antifouling coatings.
