Abstract :

Conducting polymer Composites are required in many engineering applications, especially, for the design of microwave absorbers and microwave shielding to ensure electromagnetic compatibility and electromagnetic immunity. In this paper, we report the synthesis of conducting polymer i.e. polyaniline (PANI) and its composites. Polyaniline is prepared by oxidation of aniline and the polyaniline composites were prepared by in situ polymerization method with dispersion of Ta2 O5 . For the microwave measurements these samples were made in rectangular pellet of thickness 0.3mm using Pye–Unicam dye. The permittivity and return loss of composites in the frequency range 8–12 GHz is discussed in this paper and the maximum absorption is observed in 10 wt% Ta2 O5  in PANI,
