Marine biofouling negatively impacts marine industries and ship navigation. However, current coatings are based on a single antifouling mechanism, which is insufficient to cope with the complex ever-changing environment. Herein, multifunctional were developed using material system containing perfluoropolyether caprolactone chains. First, an acrylic resin side chains was synthesized as liquid-repellent component then degradable cross-linked network constructed by bridging polycaprolactone Surprisingly, not only effectively improved tensile strength but also provided flexibility resin. Thus, coating exhibited satisfactory mechanical stability low roughness (4.06 nm) during dynamic polishing. It worth noting that surface energy (SE) (22.0 mJ·m

Abstract As maritime transport becomes increasingly important, metal corrosion results in significant economic losses. Superhydrophobic materials have potential for prevention. However, poor compatibility between superhydrophobic and resin reduces the long‐term resistance. Interfacial strengthening cells (IS‐Cells) are designed to maintain superhydrophobicity retain active hydroxyl groups participating resin‐curing. IS‐Cells also contribute achieving maze effect. A novel anti‐corrosion IS coating is fabricated by compatible epoxy. coatings feature smooth surfaces vertical compactness, protecting against liquid gaseous corrosive medium.
