Abstract

CIP particles first have been coated with SiO2 shell by a Stober process, then grafted the polyaniline by in-situ polymerization to prepare CIP/SiO2/PANI core-shell composites, and the composites are composed the dielectric loss properties with the magnetic loss properties. It is observed that PANI are on the surface of CIP/SiO2 particles from the SEM image, XRD patterns further confirm that the CIP/SiO2/PANI composites are synthesized successfully. In comparison with CIP, the complex permittivity of CIP/SiO2/PANI composites have certain enhancement in 8-12 GHz frequency range, but it has a very small impact on the complex permeability. On the basis of the Electromagnetic Wave Absorbing Theory, the composites could prepare high-performance absorbing coating based on λ/4 type design, and the coating is below -10dB in the whole X-band, which could be used for architectural space electromagnetic radiation protection.
