Conducting polymer nanocomposites of polyphenyl amine with bariumferritenanoparticles(50–70nm) have been synthesized via emulsion polymerization. The complex permittivity, permeability, and microwave absorption properties of the composite were studied in the 12.4–18GHz (Ku band) frequency range. The composite has shown high shielding effectiveness due to absorption (SEA) of 28.9dB (∼99.9%), which strongly depends on dielectric loss, magnetic permeability, and volume fraction of bariumferritenanoparticles. The high value of SEA suggests that these composites can be used as a promising radar absorbing materials.
