Abstract

Polyaniline nanocomposite films were prepared with various weight percentages by in situ polymerization method using aniline, ammonium per sulfate, and cdo as starting materials. The formations of pani and pani/cdo/ZnO composites with regards to the structural and microstructural properties of the materials were investigated by SEM techniques. The DC conductivity of Pure Pani and its composites have been measured in the temperature range from 30°C to 160°C.

Highlights

Among conducting polymers, polyaniline family called synthetic metals
Extensive literature review suggests persulphate at room temperature, followed by the that the considerable efforts have been made by separation of PANI hydrochloride precipitate by researchers all over the world in improving the conductivity of polyaniline by various doping techniques, but little is known about the dielectric properties of conducting polymers associated with conduction mechanism [4] .On doping these conjugated polymers show very high conductivity similar to metals

Summary

Introduction

Polyaniline family called synthetic metals. They combine the electrical properties of metals with the advantage has attracted much attention of scientists world- of polymers such as smaller weight, greater wide because of their ease of synthesis, unique workability, resistance to corrosion and lower cost conduction mechanism, high environmental [5-7]. Extensive literature review suggests persulphate at room temperature, followed by the that the considerable efforts have been made by separation of PANI hydrochloride precipitate by researchers all over the world in improving the conductivity of polyaniline by various doping techniques, but little is known about the dielectric properties of conducting polymers associated with conduction mechanism [4] .On doping these conjugated polymers show very high conductivity similar to metals. PANI– Cdo/ZnO composites containing various weight percentage of Cdo/ZnO (10 %, 20 %, 30 %, 40 %, and 50 %) in PANI were synthesized
