摘要：

Marine biofouling poses a threat to marine facilities. In this work, a quaternary ammonium salt (E54-QAS) was synthesized from triethylammonium hydrochloride and epoxy resin E-54, which was then incorporated into a polyurethane (PU) prepolymer to fabricate an antifouling coating. The coating exhibited a bonding strength as high as 3.12 MPa and impact resistance of 90 kg as well as excellent antibacterial efficiency against Pseudomonas aeruginosa at an E54-QAS content of 4.2%. Moreover, the antimicrobial efficacy of the coating remained above ...
