AC Conductivity Study of Polyaniline / Dysprosium Oxide (PANI / Dy2O3) Composites

Sangshetty Kalyane

Abstract :

The conducting polyaniline / Dysprosium oxide (PANI / Dy2 O3 ) composites were synthesized by single step in situ polymerization technique by placing finely grinded powder of Dy2 O3  during the polymerization of aniline. The formation of mixed phases of the polymer together with the conducting emeraldine salt phase was confirmed by spectroscopic techniques like XRD, FTIR & SEM images indicated a systematic morphological variation of particles aggregated in the composite matrix as compared to the PANI. AC conductivity of these composites were investigated in the frequency range 50 Hz to 5MHz. It is found that AC conductivity obeyed the power law index and the variation of conductivity with wt% of Dy2 O3  could be related to conductivity relaxation phenomenon.
