Investigation on Structural, Electrical and Dielectric Properties of Polyaniline/ZrO2 Composite
The effect of ZrO2 nanoparticles on the structural, electrical, and dielectric properties of polyaniline was studied. ZrO2 nanoparticles with an average size of 8 nm were synthesized by a simple precipitation method and their tetragonal and monoclinic crystalline phase was confirmed. Polyaniline and its nanocomposite with ZrO2 have been synthesized by chemical oxidation method using CH3COOH as a doping agent and APS as an oxidant. The synthesized composites were analyzed by infrared spectroscopy, X-ray diffraction, scanning electronic microscopy, AC conductivity, dielectric and impedance spectroscopy. In Nyquist plots, systematic decrement in the semicircle size was observed with growth of ZrO2 content. The dielectric constant in the PANI/ZrO2 composite has been increased with an increase in weight content of ZrO2 in PANI matrix and exhibited the Maxwell–Wagner–Sillars effect.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
