摘要：Iron powder (IP) was modified by silane coupling agent to form coupling agent funtionalized iron powder (CIP). Then surfactant polyvinylpyrrolidone was adsorbed onto the surface of CIP. Finally, the aniline was polymerized onto CIP surface. Polyaniline (PANI) shell was formed on metal iron surface and it was verified by transmission electron microscopy (TEM) characterization. The PANI-CIP core-shell nanoparticles were used as fillers within poly(vinylidene difluoride) (PVDF) to prepare the (PANI-CIP)-PVDF dielectric composites. The dielectric constant of (PANI-CIP)-PVDF was obviously larger than that of IP-PVDF composite. 20%-(PANI-CIP)-PVDF showed high dielectric constant of 72.35 at 0.1 Hz, which was almost 3.5 times larger than that of 20%- IP-PVDF.
