Preparation and characterization of nanoflake composite multi core–shell SrFe12O19/Fe3O4/PEG/PPy

Nanoflake composite multi core–shell SrFe12O19/Fe3O4/PEG/Polypyrrole was synthesized by in situ polymerization method. In this paper, the fabrication of SrFe12O19 nanoflake is as first core by solgel method. Then fabricated a shell layer from magnetic nanoparticles of Fe3O4, which synthesized by coprecipitation technique, onto the SrFe12O19 nanoflake. Polyethylene glycol (PEG) as a polymer layer and as second shell was coated onto the before core-shell. Than core–shell SrFe12O19/Fe3O4/PEG was used as template for the preparation of SrFe12O19/Fe3O4/PEG/Polypyrrole composite. Final composite has a conductive property among 4.23
