International. A new type of modified graphene oxide coating that was prepared by anchoring a urea-formaldehyde (UF) resin prepolymer on the graphene oxide sheets via in situ polycondensation showed a surprising effect.
Researchers from China claimed that the modified graphene oxide (GO) sheets were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction experiment, Fourier transformation infrared spectroscopy, sedimentation testing, and electrochemical impedance spectroscopy.
An important finding was that the superior compatibility of UF resin with epoxy resin retained the high dispersion of modified GO sheets in the polymer matrix. The results further revealed that the modified GO sheets significantly reinforced the corrosion protection properties of epoxy coatings on carbon steel substrate.
