Synthesis and Characterization of Itaconic Acid Doped Polyaniline/SnO2 Nanocomposites

Abstract Composites comprised by polyaniline doped with itaconic acid and tin oxide (SnO 2 ) were prepared by in situ polymerization method. Aniline was polymerized in the presence of SnO 2 to form inorganic–organic nanocomposite materials, in which SnO 2 nanoparticles were embedded within polyaniline. The chemical structure, crystallinity, morphology, thermal stability, conductivity, and microwave absorbing properties were characterized. The morphology of the composites is nanorod and polyaniline enwraps SnO 2 to form a kind of core-shell nanostructure. Moreover, the composites have better thermal stability and microwave absorbing properties.
