Polyacrylamide (PAAM) nano silica inclusions composites were prepared having different ratios of nano silica. The silica inclusions were either modified or unmodified. The nanocomposite films were characterized by transmission electron microscope (TEM) and infrared spectroscopy (IR). The dielectric behavior of the composites had been investigated as a function of the concentration of the nano silica inclusions. The results show that the dielectric constant and dielectric loss of the nanocomposites are smaller than those obtained for the neat polymer. As the concentration of the surface-modified nano silica inclusions increases, the dielectric constant decreases. This behavior may be attributed to the successful interaction between the polymer and the surface of the nano silica inclusions. As would be expected, the results thus obtained are a clear manifestation of the role of surface treatment of the filler inclusions and subsequently the role played by the interface on the properties of the composites. |
