Abstract:
Polyvinylidene fluoride-carbonyl iron powder (PVDF-CIP) composites with different carbonyl iron powder loading were developed for electromagnetic interference shielding applications in the X band. Shielding properties improved with increase in carbonyl iron powder content and uniform electromagnetic shielding effectiveness of about 20 dB is obtained for PVDF-50 vol% carbonyl iron powder composite over the entire X band. The magnetic and dielectric loss tangent of the composite increased with increase in carbonyl iron content. It is found that the PVDF-CIP composites shield by absorption
