Dynamic Surface Antifouling Materials
AI summary Read the abstract
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.

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.

AI summary Read the abstract
Scientists created a biodegradable, wax-based coating that keeps algae and bacteria from sticking to underwater equipment, without using toxic chemicals or plastics that break down into harmful microplastics. This matters because it could reduce ocean pollution from conventional antifouling paints while protecting marine ecosystems, including coral reefs, that eventually support seafood safety and human health.
