This study presents a novel approach to combat marine biofouling by developing a polymeric coating with integrated fouling killing, resistance, and releasing functions. The coating degrades at the surface/seawater interface, generating antifouling and zwitterionic groups for effective protection. The controllable degradation rate and synergistic antibacterial effects make this coating a promising solution to the challenge of marine biofouling.
Traditional antifouling coatings are generally based on a single antifouling mechanism, which can hardly meet the needs of different occasions. Here, a single kill-resist-renew trinity polymeric coating integrating fouling killing, resistance, and releasing functions is reported. To achieve the design, a novel monomer-tertiary carboxybetaine ester acrylate with the antifouling group N-(2,4,6-trichlorophenyl)maleimide (TCB-TCPM) is synthesized and copolymerized with methacrylic anhydride via reversible addition-fragmentation chain transfer polymerization yielding a degradable hyperbranched polymer. Such a polymer at the surface/seawater is able to hydrolyze and degrade to short segments forming a dynamic surface (releasing). The hydrolysis of TCB-TCPM generates the antifouling groups TCPM (killing) and zwitterionic groups (resistance). Such a polymeric coating exhibits a controllable degradation rate, which increases with the degrees of branching. The antibacterial assay demonstrates that the antifouling ability arise from the synergistic effect of attacking and defending. This study provides a new strategy to solve the challenging problem of marine biofouling.
