Abstract
In this work, chitosan was used as powerful chelating agent and an excellent template for synthesis of metal oxide nanoparticles. Chitosan-Pb and Chitosan-Bi nanoparticles have been synthesized by incorporating PbO/BiO nanoparticles within the chitosan matrix using a simple solution cast method. Dielectric and optical properties of the nanocomposite film were studied. Moreover, the effect of temperature on the dielectric properties of the hybrid film was determined. The absorption and transmittance were measured for the prepared samples by using UV–Vis spectrophotometer. The optical parameters such as refractive index, absorption coefficient, energy band gap, dispersion energy, oscillation energy, and the skin or penetration depth for the chitosan-PbO/-BiO nanocomposite were obtained.
