▎ 摘　　要

We report on the synthesis, characterization and application of highly crystalline graphene integrated polyaniline nanostructured composites as corrosion protection coatings. The coated surface showed a decline in corrosion current up to similar to 3-4 orders of magnitude in 0.1 M HCl. Composite coating with 1.92 wt.% graphene loading showed best protection. SEM images obtained after the corrosion tests reveal several pits on the coated steel surface with network like structures. A plausible mechanism of the corrosion protection mechanism of the composite coating has been proposed to explain the fate of the material in acidic environment. (C) 2016 Elsevier Ltd.
