| 英文摘要 | The synthesis of the novel environmentally benign benzimidazole derivative (HSUB) involved a series of reactions, including amidation, cyclization, and quaternization. Designed specifically for offshore oil and gas submarine pipelines, this multifunctional corrosion inhibitor combines corrosion inhibition, scale prevention, and antibacterial capabilities, reducing dependence on multiple chemical reagents. A highloading nanocontainer (HNTs-CS@HSUB) was developed, endowing the smart coating with pH-responsive gating functionality. HSUB can be delivered via two pathways-release from the coating matrix and supplementary injection-after which it adsorbs onto damaged areas, spontaneously forms a protective inhibitor film, and protects the metal substrate. Notably, X65 steel immersed in a simulated corrosive solution containing 6 & times; 10-4 mol/L HSUB at 298 K for 30 days exhibited a maximum corrosion inhibition efficiency of 93.77 %. EQCM analysis confirmed that controlled delivery significantly enhanced protective performance by densifying the inhibitor film. As a sacrificial inhibitor, its scale inhibition efficacy stems from sustained corrosion suppression and strong chelating stability with Ca2 + . This retards the formation of acidic anaerobic microenvironments favorable for sulfate-reducing bacteria (SRB) proliferation and the generation of heterogeneous nuclei. Consequently, in high-temperature and high-acidity environments, this system provides an efficient, stable, and long-lasting integrated protection solution for corrosion inhibition, scale prevention, and antibacterial defense of submarine pipelines in deep-sea gas field development.
