Synthesis of P(St-MAA)-Fe3O4/PPy core-shell composite microspheres with conductivity and superparamagnetic behaviors

► We propose a simple route for the synthesis of P(St-MAA)-Fe3O4/PPy composite materials. ► The composites exhibit excellent superparamagnetic behavior with various saturation magnetizations. ► The electrical conductivity of the composites directly depends on the PPy loading amount in the outside layer.
