Facile synthesis of Fe3O4@PPy core-shell magnetic nanoparticles and their enhanced dispersity and acid stability

Highly acid stable Fe3O4@PPy core-shell nanoparticles were synthesized using growth of polypyrrole layers on the surface of Fe3O4 core via in-situ electropolymerization and electro- deposition of Pyrrole. This method is promising to give a new alternative strategy for designing and preparing multifunctional nanomaterials with enhanced performance.81
