Abstract:

Hexanoyl chitosan-sodium iodide (NaI) complexes were prepared using solution casting method. The temperature dependence conductivity was performed in the temperature range of 303-343K. From the dielectric studies, it has been observed that the dielectric constant, εr and dielectric loss, εi increases with temperature in the lower frequency region and almost negligible in the higher frequency region. This behavior can be explained on the basis of electrode polarization. Plot of real part, Mr and imaginary part, Mi of modulus versus frequency indicates that the systems are predominantly ionic conductor. Relaxation time calculated from the peak of Mi at various temperatures appears to be thermally activated. The conductivity, σ(ω) is found to be almost frequency independent at low frequencies and became frequency dependent at high frequencies. The transference number measurement showed that the conductivity was predominantly ionic.
