Abstract

The present paper reports an approach to synthesize nano-stick shaped ferromagnetic iron oxide-polypyrrole in presence of sodium lauryl sulfate (SLS) via microemulsion polymerization. The presence of anionic surfactant SLS in polymerization influence the properties of pyrrole due to the bonding of anionic part of the surfactant molecule to the polypyrrole chains. It controls the morphology and leads to form stick shaped polymer composites decorated with Fe2O3 (10-15 nm) nanoparticles. As prepared conducting ferromagnetic polymer nanocomposites have electrical conductivity of the order of 10(-2) S/cm and saturation magnetization (M-s) value of 35 emu/g. Polypyrrole nanocomposite having weight ratio [pyrrole]/[Fe2O3] = 1: 3 shows microwave absorption as high as SEA similar to 22.5 dB (>99% attenuation) in the frequency range of 12.4-18 GHz (Ku-band)
