Silicone coatings are widely employed in marine antifouling applications due to their low surface energy. However, static environments, pure silicone ineffective preventing the adhesion of biofilms, which consist proteins, bacteria, and extracellular matrices, ultimately promoting attachment macrofouling organisms. To address limitations performance under conditions, this study introduces a silicone-based coating modified with zwitterionic polymers. Sulfobetaine (SB) segments were grafted onto side chains poly(dimethylsiloxane) (PDMS) synthesize amphiphilic polymer P(DMS-SB), was incorporated into PDMS network create an interpenetrating network-structured coating. The effectively inhibited algae through hydration effects. Compared coatings, reduced by 88%, 98.9%, 99.3%, respectively. Additionally, demonstrated excellent fouling-release properties, achieving 91.3% removal rate for settled water flow conditions reducing simulated barnacle strength 68.4%. This presents promising solution ships, offshore structures, aquaculture facilities environments significant potential widespread application.
