Abstract

Abstract:

Polyaniline/CoC₂O₄ nanocomposite with both electrical and magnetic conductivity has been synthesized by using in-situ growth of polyaniline under different conditions on the surface of nano-cobalt oxalate, which was obtained by low heating solid state reaction. The influence of reaction conditions including reactants ratio, mixing methods, type and quantity of surfactants on the morphology and structure and their electromagnetic properties of resulting composites was investigated. The products were characterized by TEM, XRD, and TG analysis techniques. The results indicate that the morphology and structure and their electromagnetic properties of nanocomposites can be effectively tuned by changing the in-situ complex conditions. The optimal experimental results were as follows: PAn/CoC₂O₄nanocomposite obtained under ultrasonication showed a maximum reflection loss of -28.8 dB at 8.6 GHz with a bandwidth of 3.2 GHz above -10 dB loss.

Key words: Polyaniline, cobalt oxalate, nanocomposite, electromagnetic properties
