Preparation and characterization of polyani-line/polyvinyl alcohol nanocomposite by laser irradiation

Polyaniline (PANI) - Polyvinyl alcohol (PVA) nanocomposite were prepared using laser irradiation method. X-ray diffraction results showed that, (PANI/PVA) nanocomposite exhibited amorphous nature of polymer. The electronic transition will be studied using Ultraviolet-Visible spectrometer (UV-Vis). The real part of dielectric constant (？) and imaginary part (ε") were studied. Also, the relaxation time was calculated.
