Development and characterization of copper doped perovskite-polymer composite through high-temperature technique.

Ceramic powders of Cu doped lead Titanate (Pb_0.5Cu_0.5TiO₃) are synthesized through a solid-state reaction method at high-temperature. Different percentage of ceramic filler into the polymer matrix was prepared by solution casting techniques. The structural studies of this polymeric composite were characterized by the X-ray diffraction technique and a tetragonal phase was found. Moreover, the surface morphology of this material was done by scanning electron microscopy. The impedance studies of this polymeric composite were characterized by an LCR meter between the frequencies range 10² and10⁶ Hz. The modulus study of the material was done between the frequency ranges 10² and10⁶ Hz. The variation of ac conductivity with frequency at different temperatures satisfied Jonscher's universal power law. [ABSTRACT FROM AUTHOR]
