▎ 摘　　要

Epoxy coatings containing polyaniline (PANI), graphene (Gr), myristic acid-modified graphene (GrMA), and PANI/Gr and PANI/GrMA nanocomposites were evaluated regarding their performance in corrosion protection of carbon steel. Scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy were applied to the characterization of epoxy nanocomposites and their performance as anticorrosive coatings. Results indicated that myristic acid provided better distribution of GrMA in the epoxy resin matrix. The GrMA coating exhibited the best performance in corrosion protection, with less damage to its structure. Graphene provided better corrosion protection and resulted in less damage to the polymeric structure.
