Confirmation of ceria-polyaniline core-shell nanostructure: An optical approach

Abstract

Nanostmctured cerialpolyaniline core shell particles were synthesized via polymerization of aniline monomers with the cerium oxide nanoparticles. Cerium oxide nanoparticles were prepared by hydroxidemedicated treatment and the shell was formed by polymerization of aniline hydrochloride with ammonium peroxydisulphate. Stmctural and optical characteristics of the prepared nanocomposites were studied separately for cerium oxide, polyaniline and core-shell ceria-polyaniline. The UV-Vis absorption spectra of the CeO 2-PANI confirmed the formation of the core-shell nanostmcture. The optical propedies of nanocomposites obtained from this method were analyzed as a function of preparation condition and the same has been reported. © 2012 Asian Network for Scientific Information.
