عنوان المقالة:تاثير اوكسيد الكرافين المحور على الخواص الكهربائية والعزلية لافلام بولي فاينيل الكحول Effect of Functionalized Graphene Oxide (FGO)on the Electrical and DielectricalProperties of PVA Films
In the presentwork,nanocomposite of poly (vinyl alcohol) (PVA) incorporated withfunctionalizedgraphene oxide (FGO) were fabricated using casting method. PVA was dispersed byvarying content of FGO (0.3, 0.5, 0.8, 1wt %). The PVA-FGO nanocomposite was characterizedby FT‐IR, FE-SEM and XRD.Frequency dependence of real permittivity (ε’), imaginary(ε’’)and a.cconductivity of PVA/FGO and PVA/GOnanocomposite werestudied in the frequency range 100 Hz-1 MHz.The experimental results showedthat the values of real (ε’)andimaginarypermittivity (ε’’)increaseddramatically by increasing theFGO content in PVA matrix.PVA/FGO(1 wt%)nanocomposite revealedhigherelectrical conductivity of 6.4×10-4Sm-1compared to 1.4×10-8Sm-1for PVA/GO
