Polyaniline Nanofiber Embedded with Y2O3 Composites Doped with Dodecyl Benzene Sulfonic Acid, Characterization and Electrical Properties

Abstract

Polymer nanocomposites of polyaniline nanofiber/Green synthesized Y2O3 (Pani/Gs Y2O3) are synthesized by in situ polymerization using dodecyl benzene sulfonic acid as a surfactant media. The Gs Y2O3 is dispersed in 1, 3, 5 and 7 weight percentages in Pani to give Pani/Gs Y2O3 composites. The Pani/Gs Y2O3 composites are characterized by Ultra Violet, Infra-Red spectroscopy and X-ray diffraction techniques. The SEM and TEM image shows the fibrous morphology of the composite. Pani nanofiber/5%Gs Y2O3 nanocomposites show highest frequency dependent conductivity, dielectric constant and dielectric loss Properties at room temperature. Such a polymer composites have EMI shielding, sensor and battery applications.
