In this work,lithium (Li)-aluminum (Al) layered double hydroxide (LDH) films modified by 4-amino-2-((hydrazine methylene) amino)-4-oxobutanoic acid (denoted as AOA acid) and/or 1H,1H,2H,2H-perfluorooctyltriethoxysilane were prepared on 6N01 Al alloy by a facile,in-situ growth method with enhanced hydrophobicity,anti-biofouling and anti-corrosion performance.The preparation is low energy consumptive and environment friendly,relying on self-assembly at ambient temperature.The structure,molecular weight and functional groups of the synthesized AOA acid were characterized by NMR spectrometer,ESI-MS spectrometer and Fourier transform infrared (FT-IR) spectroscopy.And the compositions,structure and morphology of the films were characterized by Fourier transform infrared(FT-IR) spectroscopy,glancing-angle X-ray diffraction (GA-XRD),X-ray photoelectron spectroscopy (XPS),field emission scanning electron microscopy (FE-SEM) and energy-dispersive x-ray spectrum (EDS).Water contact angle measurements (CA) and atomic force microscopy (AFM) characterization show that the films possess a micro/nanostructure with an improved hydrophobicity.Immersion test,neutral salt tests (NSS) and electrochemical impedance spectroscopy (EIS) conducted in 3.5 wt.％ NaCl solutions demonstrate the improved corrosion resistance of the films over bare Al alloy.Meanwhile,the films also possess an excellent anti-bacterial property to Escherichia coli,Bacillus subtilis and sulfate-reducing bacteria.
