제목 Highly Crystalline Graphene Integrated Polyaniline Nanostructured Composites for Protecting Steels from Corrosion in Acidic Environment
초록 We report on synthesis, characterization and application of highly crystalline graphene integrated polyaniline (PaniGn) nanostructured composites as corrosion protection coatings. The coated surface showed a decline in corrosion current up to ~3-4 orders of magnitude in 0.1 M HCl. SEM reveals several pits on the surface after the corrosion tests. To explain the observations and understand the fate of the composite coating during corrosion, we present here a molecular model using quantum chemical calculations based on density functional theory. The model presents a plausible mechanism of the protection behavior of the composite coating.
