Abstract:

This paper summarized the main preparation methods of polypyrrole?coated inorganic nanoparticle composites with a core?shell structure and reviewed their research progress in the field of electromagnetic shielding. Their electromagnetic shielding performance and corresponding shielding mechanism were discussed, in particular for metal, oxygen/carbon/nitride compound and carbon?based materials as core components. The results suggested that the core?shell structure not only integrated the superiority of polypyrrole and inorganic nanoparticles, but also generated a synergistic effect. This method was proved to be an effective way for the fabrication of new electromagnetic shielding materials.

Key words: polypyrrole, inorganic nanoparticle, core-shell structure, electromagnetic shielding performance
