Abstract:

PVA/CuI polymer composite samples have been prepared and subjected to characterizations using FT-IR spectroscopy, DSC analysis, and ac spectroscopy and dc conduction. The FT-IR spectral analysis shows remarkable variation of the absorption peak positions whereas DSC illustrates a little decrease of both glass transition temperature ,Tg , and crystallization fraction , χ , with increasing CuI concentration. An increase of dc conductivity for PVA/CuI nano composite by increasing CuI concentration is recoded up to 15 wt% , besides it obeys Arhenuis plot with an activation energy in the range 0.54– 1.32 eV. The frequency dependence of ac conductivity showed power law with an exponent 0.33
