Stable magnetic nanofluids containing Fe 3 O 4 @Polypyrrole (PPy) nanoparticles (NPs) were prepared by using a facile and novel method, in which one-pot route was used. FeCl 3 ·6H 2 O was applied as the iron source, and the oxidizing agent to produce PPy. Trisodium citrate (Na 3 cit) was used as the reducing reagent to form Fe 3 O 4 NPs. The as-prepared nanofluid can keep long-term stability.
