Influence of Nickel Oxide Nanoparticle on the Structural, Electrical and Dielectric Properties of Polypyrrole Nanocomposite

摘要

Conducting polypyrrole and nickel oxide nanoparticle incorporated polypyrrole nanocomposite was synthesised using in situ chemical oxidative polymerisation. The structural property of synthesised samples was characterised using x-ray diffraction method. The dielectric constant, loss and AC conductivity of composite was measured as a function of frequency in the range 40Hz - 1MHz at different temperature. The electrical conductivity of pure PPy and PPy-NiO is found to be 2.24 ×10~(-5) S/cm and 0.163 S/cm. The influence of nickel oxide nanoparticle may responsible for enhances the conductivity of polypyrrole nanocomposite.
