摘要：Nanostructured materials are attracting interests and applications, thus;physical and electrical properties of Polymethylmethacrylate (PMMA) nanocompositematerials under various thermal conditions are currently being studied. The dielectricbehavior of new nanocomposite materials of Polymethylmethacrylate filled with nanoclayor nano-fumed silica has been measured at various frequency (0.1 kHz - 1 kHz) andtemperatures (20°C-60°C). Dielectric spectroscopy has been used to characterize ionicconduction and state the effect of filler concentration on the dielectric permittivity anddielectric losses, therefore; the relative permittivity and the loss tangent are measured bydielectric spectroscopy for Polymethylmethacrylate with and without nanofillers.Finally, it has been compared between dielectric properties of newPolymethylmethacrylate nanocomposites which prepared by adding nanofillers of clayor fumed silica with different concentrations under various temperatures
