“…Therefore, in this work, a synergistic strategy was proposed and achieved by copolymerizing several functional monomers. MMA, EA, and BA were used to render the coating with durability and strong mechanical and adhesion properties. − TBSM can render the coating a stable hydrolysis rate for stable eugenol release. − PVP is a neutrally charged polymer with strong hydrophilicity and antifouling properties, as well as stability against oxidation . EM can covalently incorporate eugenol moieties into the coating, render coating contact inhibition properties.…”

The development of environmentally friendly and long-term marine antifouling coating remains a huge challenge in the maritime industry. For this purpose, we developed a novel and efficient antifouling coating based on a synergistic strategy, incorporating contact inhibition, fouling repelling, and antifouling properties. Results demonstrated that the coating could efficiently resist the adhesion of protein, bacteria, and Navicula diatoms. More importantly, marine field tests showed the coating could efficiently inhibit biofouling for at least 8 months. This approach paves a new way for the development of environmentally friendly and long-term antifouling coating.

“…Another eco-friendly approach to antifouling is the fouling-releasing coating [210][211][212][213]. For example, silicone-based polymers can be developed into a fouling-releasing coating to release attached bio-foulings easily from the coating surface [214].…”

Organic coatings for marine applications must have great corrosion protection and antifouling performance. This review presents an overview of recent investigations into coating microstructure, corrosion protection performance, antifouling behavior, and evaluation methods, particularly the substrate effect and environmental influence on coating protectiveness, aiming to improve operational practice in the coating industry. The review indicates that the presence of defects in an organic coating is the root cause of the corrosion damage of the coating. The protection performance of a coating system can be enhanced by proper treatment of the substrate and physical modification of the coating. Environmental factors may synergistically accelerate the coating degradation. The long-term protection performance of a coating system is extremely difficult to predict without coating defect information. Non-fouling coating and self-repairing coatings may be promising antifouling approaches. Based on the review, some important research topics are suggested, such as the exploration of rapid evaluation methods, the development of long-term cost-effective antifouling coatings in real marine environments.

“…Ideal marine coatings should be able to simultaneously resist the initial settlement of marine organisms (antifouling property) and have low adhesion strength with the organisms (fouling-release property) without environmental threats. ,, Recently, many nontoxic strategies have been extensively explored to meet the challenge of marine biofoulings. − For example, the controlled surface topography is applied to influence the settlement behavior of marine organisms; − the surfaces are modified by fouling-deterrent bioactive molecules, or antifouling zwitterionic groups, and so forth. − Modifications of zwitterionic materials have achieved excellent mechanical stability, tunable elasticity, or long-term anti-biofilm properties. − In recent years, amphiphilic materials presenting both antifouling and fouling-release properties have been a promising marine coating. ,− The amphiphilic coating surfaces incorporate the hydrophilic segments (e.g., polyethylene glycol, PEG) to resist organism attachment with the hydrophobic segments (e.g., polydimethylsiloxane, PDMS) to reduce the adhesion strength. − However, the ether linkage in PEG is susceptible to thermal/oxidative chain scission, significantly reducing the protein resistance. − Moreover, hydrophobic PDMS cannot prevent the formation of marine slime layers (mainly composed of protein, bacteria, and diatoms) because of the hydrophobic interaction between slime-based marine organisms and PDMS materials. , …”

“…Subsequently, the amphiphilic copolymer is blended into a crosslinked PDMS matrix to develop a highly efficient marine antifouling coating. Because the pyrrolidone units can tightly bind water molecules, PVP presents a high hydrophilicity to form a strong hydration layer, which can eliminate the electrostatic force and hydrophobic interaction between the coating surface and biomolecules. , Therefore, hydrophilic PVP segments in PVP–PFA–PDMS copolymer can effectively resist the settlement of fouling organisms. More importantly, PVP has been reported to possess a superior long-term stability even in harsh conditions (e.g., 3% of H 2 O 2 solution for 100 h at 60 °C) .…”

The development of environmentally friendly and highly efficient antifouling coatings is vastly desirable in the marine industry. Herein, we prepared a novel amphiphilic block copolymer that combined hydrophilic polyvinylpyrrolidone (PVP) with hydrophobic poly(1-(1H,1H,2H,2H-perfluorodecyloxy)-3-(3,6,9-trioxadecyloxy)-propan-2-yl acrylate) (PFA) and polydimethylsiloxane (PDMS). The amphiphilic copolymer (PVP−PFA−PDMS) was blended into a cross-linked PDMS matrix to form a set of controlled surface composition and surface-renewal coatings with efficient antifouling and fouling-release properties. These coatings incorporated the biofouling settlement resistance ability attributed to the hydrophilic PVP segments and the reduced adhesion strength attributed to the low surface energy of fluorine−siliconcontaining segments. As expected, the coatings showed an excellent antifouling performance against bacteria and marine unicellular Navicula parva diatoms (98.1 and 98.5% of reduction, respectively) and fouling-release performance against pseudobarnacle adhesion (84.3% of reduction) compared to the pristine PDMS coating. Moreover, a higher-content PVP-based coatings presented higher ability to resist biofouling adhesion. The nontoxic antifouling coating developed in this paper hold the potential to be applied in a variety of marine industrial facilities.
