Current researches had shown that the electrical conductivity of most polymers depend on the method of
its preparation and type of fillers. This research therefore aimed at studying the electrical properties of
polyaniline carbon nanotubes nanocomposite prepared by hand mixing and decoration methods. The
effect of preparation method on electrical properties of polyaniline containing Carbon Nanotubes (CNTs)
and silver nanoparticles was studied. The formation of Ag NPs was confirmed by XRD. The ACconductivity,
dielectric permittivity (e’) and dielectric loss (e”) of (CNTs/PANI/Ag) nanocomposites
have been measured in the temperature range from 298 to 433 K and frequency range from 10 to 100
kHz. The Ag-CNTs improved the electrical conductivity and dielectric properties of polyaniline. The
electrical conductivity of the CNTs/Ag/PANI nanocomposite prepared by decoration method is higher
than composites prepared by mixing method. |
