AC Conductivity Characteristics of Polymer/Metal Oxide Thin Films
Organic/inorganic polymer composite films containing poly (methyl-methacrylate) (PMMA)/ ferric oxide Fe2O3 were prepared following solution casting technique. Dielectric Properties of films has been studied using LCR meter at room temperature 26ºC. Also optical properties have been studied using digital abbey refractometer. The dielectric behavior of films have been studied as a function of concentration, and at lower frequencies over the range 100 Hz-25 KHz, The results elucidate that 70:30 and 50:50 wt% of PMMA/Fe2O3 composite films posses optimal conducting properties due to observed electronic polarisability dip at 40Wt% of Fe2O3.
