| 英文摘要 | In this work, two-dimensional hexagonal boron carbonitride nanosheets co-functionalized with polydopamine (PDA) and 3-aminopropyltriethoxysilane (KH550) (abbreviated as Fh-BCNNS) are introduced as nanofillers for promoting the fouling and physical barrier resistance of solvent-based epoxy coatings. The material characterization conducted with X-ray techniques of photoelectron spectroscopy and diffraction as well as Brunauer-Emmett-Teller confirm that the synthesized h-BCNNS has 353 m(2)/g specific surface area with microporous structure, while field emission scanning electron microscopy and Fourier transform infrared spectroscopy indicate that the co-functionalization is successfully achieved. After dispersing the Fh-BCNNS in the epoxy matrix at 0.3, 0.6, and 1.0 wt% followed by mixing with the curing agent, the coating is applied by a spray method on the steel surface. The data derived by electrochemical impedance spectroscopy show that the optimum corrosion resistant properties is achieved by loading 0.6 wt% Fh-BCNNS, and the coating resistance of the optimized nanocomposite is 3.7 x 10(7 )and 2.85 x (10)(6)omega.cm(2) after immersion in the corrosive electrolyte of 3.5 wt% NaCl aqueous solution for 1 day and 28 days, respectively. Furthermore, density functional theory (DFT) alongside the experimental investigations proves the mechanisms involved in corrosion protection properties through considering interactions and electronic properties. For EP/Fh-BCNNS@F-ZnO nanohybrid, the value of Z(f)= 0.01 Hz of EP/Fh-BCNNS@F-ZnO hybrids after 1 day and 4 weeks of immersion, are 9 x 10(7) and 3.3 x 10(7) omega.cm(2) which are two order of magnitude higher than EP/Fh-BCNNS. According to anti-fouling results, the growth rate of algae is less than 10% for the EP/Fh-BCNNS@F-ZnO sample and between 30% and 60% for the control sample (EP/Fh-BCNNS at 0.6 wt%) after 28 days of immersion. |
