Electrical and Dielectric Properties of Copolymer Poly[trans-Dichlorobis(carboxyl penta methylene amine)bisphenoly- A Platinum(II) terephthalate] (PDPT)

Electrical and dielectric properties of Poly[trans dichlorobis (carboxylpentamethylene amine bisphenoly A)platinum(II) terephthalate](PDPT) have been investigated as a function of temperature, to study the mechanism of electrical conduction, the current was measured by applying d.c voltage in the range(1-120V)at various thermostatically controlled temperature(308-383K).The results obtained predict the variable hopping range(VRH)conduction mechanism .Futher,the conductivity of sample increase with increased temperature and applied voltage indicated that the sample has semiconducting behaviour and the value of conductivity is order of magnitude 3.72x10-13 (S/cm) at R.T with activation energy 0.82eV to transport the electrons from valance band to conduction band .The dielectric constants of the sample at various temperatures have been calculated which increased with increasing in temperature above 340K due to increase in density of the dipole orientation .
