Abstract: In this study, Kaolin nanoparticles with different percentages (0, 1, 3, 4 and 7) wt.% was used as reinforcing phase in PolyMethyl Methacrylate (PMMA) matrix to form nanocomposite films. PVA solution used as a coated layer covered the nano-kaolin applied as a filler. The DC electrical conductivity (σdc) increases with increasing of modified nano-kaolin concentrations and Temperature (T). The AC electrical conductivity (σac) increases with increasing of modified nano-kaolin concentrations and Frequency (F). The dielectric loss and dielectric constant (ε) decrease with increasing of nano-kaolin. The activation Energy (Eact) decreases with increasing of nano-kaolin content.
