Electrical impedance spectroscopy investigation of surfactant-magnetite-polypyrrole particles

Real part of the impedance measured at 1 MHz of the SDS-Fe3O4-PPY, indicating the existence of two different sets of electrical-and possibly structural-characteristics for the SDS-Fe3O4-PPY aggregates dispersed in solution, mainly associated with the reciprocal change in the relative contents of the polymer and magnetite.
