Dielectric material based on hybrid PANI-metal nanocomposites always gained an immense research interest due to its unique properties. Herein, we have synthesized iron oxide nanoparticles embedded two different binary transition metal doped PANI nanocomposites via simple in situ rapid mixing chemical oxidative polymerization method. Morphological, structural, electronic and chemical composition of the composites were systematically studied. The influence of dopant concentration in tuning PANI surface from flake like to spherical bead like morphology was analysed by high resolution transmission electron microscopy. Moreover, dielectric parameters as function of frequency have been investigated at room temperature in a frequency range 100Hz–2MHz and the result showed that the as prepared flake like nanocomposites - 0.3 M Cu-Fe-PANI and 0.7 M Mn-Fe-PANI systems are promising dielectric materials.
