This cover picture shows that the continuously changing surfaces of Dynamic Surface Antifouling (DSAF) materials can effectively prevent microorganisms from landing and adhering. Due to the degradation of the main chain and the hydrolysis of the side chain, the surface renewing is not driven by external force, so the DSAF materials have good antifouling ability even under static conditions. They are also eco-friendly since such degradation yields low molecular weight molecules instead of microplastics. DSAF provides a general strategy to defeat marine biofouling. More details are discussed in the article by Zhang et al. on page 2881—2888.
