Preparation and Electromagnetic Properties of CIP/SiO₂/PANI Composites

Abstract:

CIP particles first were coated with SiO₂ shell by the Stober process , then grafted the polyaniline by in-situ polymerization to prepare CIP/SiO₂/PANI core-shell composites. The CIP/SiO₂/PANI composites are composed the dielectric loss properties with the the magnetic loss properties, the morphologystructure and electromagnetic properties are characterized by SEMXRD and vector network analyzer, respectively. It is observed that SiO₂ and PANI are on the surface of CIP particles, XRD patterns further confirm that the CIP/SiO₂/PANI composites are synthesized successfully, and that interaction between components exist in the polymerization. In comparison with CIP, the complex permittivity of CIP/SiO₂/PANI composites have certain enhancement in 2-18GHz frequency range, but it has a very small impact on the complex permeability.
