“…Different divinyl monomers were used as branching points including methacrylic anhydride (MAAH), N,N′-adipic bis(diacetone acrylamide hydrazone) (DAA 2 H), and ethylene glycol dimethacrylate (EGDMA). 50 As MAAH content increased, the degradation rate of the polymer increased, and it showed the following trend: EGDMA< MAAH< DAA 2 H. Antibacterial and antidiatom assays indicated that the coatings efficiently inhibited the adhesion of the marine bacteria Pseudomonas sp. and the diatom Navicula incerta because of the synergistic effects of branching point cleavage and zwitterion self-generation.…”

Conspectus Marine organisms such as barnacle larvae and spores of algae adhere to underwater surfaces leading to marine biofouling. This phenomenon has numerous adverse impacts on marine industries and maritime activities. Due to the diversity of fouling organisms and the complexity of the marine environment, it is a huge challenge to combat marine biofouling, which limits the development and utilization of marine resources. Since the International Marine Organization banned the use of tributyltin self-polishing copolymer (SPC) coatings in 2008, the development of an environmentally friendly and efficient anti-biofouling polymer has been the most important task in this field. Tin-free SPC is a well-established and widely used polymer binder for anti-biofouling coating today. Being a nondegradable vinyl polymer, SPC exhibits poor anti-biofouling performance in static conditions. Even more, such nondegradable polymers were considered to be a source of microplastics by the International Union for the Conservation of Nature in 2019. Recently, numerous degradable polymers, which can form dynamic surface through main chain scission, have been developed for preventing marine biofouling in static conditions. Nevertheless, the regulation of their degradation and mechanical properties is limited, and they are also difficult to functionalize. A new polymer combining the advantages of vinyl polymers and degradable polymers is needed. However, such a combination is a challenge since the former are synthesized via free radical polymerization whereas the latter are synthesized via ring-opening polymerization. In this Account, we review our recent progress toward degradable vinyl polymers for marine anti-biofouling in terms of polymerization methods and structures and properties of polymers. First, we introduce the strategies for preparing degradable vinyl polymers with an emphasis on hybrid copolymerization. Then, we present the synthesis and performance of degradable and hydrolyzable polyacrylates, degradable polyurethanes with hydrolyzable side groups, and surface-fragmenting hyperbranched polymers. Polymers with degradable main chains and hydrolyzable side groups combine the advantages of SPC and degradable polymers, so they are degradable and functional. They are becoming new-generation polymers with great potential for preparing high-efficiency, long-lasting, environmentally friendly and broad-spectrum coatings to inhibit marine biofouling. They can also find applications in wastewater treatment, biomedical materials, and other fields.

“…Three kind of divinyl monomers including methacrylic anhydride (MAAH), N , N ′‐adipic bis(diacetone acrylamide hydrazone) (DAA 2 H), and ethylene glycol dimethacrylate (EGDMA) were used. [ 53 ] It shows the degradation rate and mass loss of the polymer increased with the branching point content. For the same branching point content, the more breakable sites in branching points, the greater the mass loss (EGDMA < MAAH < DAA 2 H).…”

Comprehensive SummaryThe colonization of marine microorganisms, animals and plants on underwater surface forms marine biofouling. It has profound effects 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 marine 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 antifouling efficiency. This article reviews the development of dynamic surface antifouling materials.What is the most favorite and original chemistry developed in your research group?Synthesis of marine anti‐biofouling polymers.How do you get into this specific field? Could you please share some experiences with our readers?I happened to read a paper about marine biofouling on the internet three months later after I joined University of Science and Technology of China (USTC). Its adverse effects on marine industry and marine activities shocked me very much! No doubt, it makes great significance for our country and society to solve the problem. It is a challenge, but I like challenge, and I decided to get into this field. Realizing that the key is to develop new polymer resin, I was confident that I was able to solve the problem with my polymer chemistry and physics background. Actually, it is not easy. I have spent about 20 years in this project since then.What is the most important personality for scientific research?Curiosity, interest, concentration and persistence. How do you keep balance between research and family?I make a plan and organization for everything so I can keep a balance between family and work.Who influences you mostly in your life?Prof. Ming Jiang and Prof. Chi Wu, who are my PhD and post‐doctor supervisors, respectively.
