▎ 摘　　要

Modified montmorillonite/graphene oxide composites (AM@GO) were prepared by a hydrothermal method with silane coupling agent-modified montmorillonite (APTES@MMT) and combined with GO. The structures of the composites were characterized by FTIR, XRD, Raman spectroscopy, BET analysis, and SEM. The results showed that the composites had increased interlayer spacing and formed a loosely laminated stacked structure. The specific surface area (31.6863 m(2)/g) and pore volume (0.0104 cm(3)/g) of the composites increased. The hydrophobic and anticorrosive properties of the composite coatings were investigated and compared to the epoxy coating. The composite coatings (AM@GO/EP) had larger contact angles and smoother surfaces than the epoxy coating (EP). After 30 days of immersion, the value of |Z|(0.01 Hz) was approximately 10(11) omega cm(2), which had changed slightly since initial immersion. Mechanistic analysis shows that the improved corrosion resistance of the composite coatings was due to the high specific surface area of the 2D material, the oxygen-containing groups of GO, the amino groups of APTES@MMT and the synergy between the MMT and the GO nanosheets.
