Magnetic and conducting Fe3O4-polyaniline (PANI) nanoparticles with core-shell structure have been prepared in the presence of Fe3O4 magnetic fluid in aqueous solution containing dodecylbenzene sulfonic acid sodium salt (NaDS) as a surfactant and dopant. The conductivity of the composites at room te...
