| Abstract | ||||
| In the sitting study, Partially- reduced graphene oxide P(GO) was prepared from the graphite powder according to the modified Hummers d PVA / α-Al2O3/ P(GO) were prepared by casting method with compositions (w/w between P(GO) and PVAα-Al2O3/: 0%, 0.3%, 0.9% and 1.5%). The samples were recognized by X-ray diffraction (XRD), FTIR analysis and the electric properties were studied. The XRD pattern and FTIR analysis showed that the as prepared P(GO)is in pure single phase. The XRD patterns and FTIR analysis of P(GO)/ PVA/ Al2O3composites confirmed the formation of P(GO)/ PVA\α-Al2O3 composite films without any impurities. FTIR analysis of P(GO)/ PVA composites confirmed the presence of the two phases without any other phase. The temperature dependence of dielectric constant (έ) as a function of frequencies for P(GO)/ PVA/α-Al2O3 composites was measured and indicated that the dielectric constant decrease with increasing frequency and increase gradually with increasing temperature. The temperature dependence of ac. electrical conductivity as a function of frequencies for P(GO)/ PVA/α-Al2O3 composites was determined. The results showed that presence of two different conduction mechanisms. | ||||
