文摘

Calcium carbonate nanoparticles (nano-CaCO₃) anchored graphene oxide (GO) sheet nanohybrids (GO-CaCO₃) are fabricated, and their structure can be measured by scanning electron microscope, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction and Fourier-transform infrared spectroscopy analysis. Afterwards, composite epoxy coatings, filled with GO and GO-CaCO₃ nanohybrids, are prepared via a curing process. The dispersion and anticorrosive properties of composite epoxy coatings are investigated. The results reveal that GO-CaCO₃ nanohybrids achieve a homogeneous dispersion as well as reinforce corrosion resistance of epoxy coatings. Furthermore, the anticorrosive mechanisms are tentatively proposed for the GO-CaCO₃/epoxy coatings. Copyright
