On the Electrical and Optical Properties of Polycarbonate /MNCl2 Composite
ABSTRACT
The nature of the MnCl2 salt as a filler to polycarbonate , including their composition, particles dimensions and homogeneity of distribution have been studied using different spectroscopic techniques (XRD, DSC and TGA). A slight increases in the chain-chain separation due to the interaction of the MnCl2 salt with the polycarbonate chains was observed , while a decrease in the optical energy gap (Eopt ) of the polycarbonate polymer with increasing the salt concentration was detected .However employing impedance spectroscopy in the frequency range 10Hz up to 106 Hz. reveals an increase in the dielectric permittivity and conductivity with increasing salt content
