Abstract In the present work, we report a new method to prepare rGO-Fe3O4-PANI ternary nanocomposites through simultaneous in-situ reduction of stabilized Fe3O4nanoparticles on the GO nanosheets with aniline monomers but without using any secondary reducing reagent, and then in-situ polymerize the aniline on the rGO/Fe3O4 surface. The rGO/Fe3O4/PANI could effectively improve the waterborne acrylate-amino coatings’ anticorrosion performances due to the efficient physical barrier formed between the different components: the enhanced passivation catalysis of PANI in rGO/Fe3O4/PANI nanocomposites and the p–n junction established between the PANI and Fe3O4 interface.
