Abstract	This study investigates the effect of varying loading percentage of MgO on the dielectric constant of Poly (vinylideneflouride)/Magnesium Oxide (PVDF/MgO) nanocomposite thin films. PVDF/MgO nanocomposite spin coated thin films were successfully fabricated and characterized. PVDF and nanocomposites solutions with loading percentage of MgO at 3, 5, 7, 9, and 11% were spin coated on Al-glass substrates at 1500rpm. The optimum percentage of PVDF/MgO thin film obtained from the dielectric measurement was 7%. The dielectric constant of PVDF/Mg(7%) nanocomposite at frequency $10^{3}$ Hz was 21, with low dielectric loss and absence of visible film defects, as evident by FE-SEM images. In FTIR, broad bonding peaks at 840 and 880 $cm^{−1}$ can be observed. Both bonding represented the -CH2 and -CF2 groups of PVDF, which indicated high β-phase content that attributed to the increment in the dielectric constant of PVDF/MgO(7%) nanocomposite. The PVDF/MgO(7%) nanocomposite is favorable for low frequency electronic application such as capacitor.
