Abstract

Abstract: Polyaniline doped with rare earth chloride was synthcsized in organic solvent and identified by clemental analysis and ithered spectroscopy. The experimental results show that there exist both doping and complexation at the same time in the resulting product. When pH<4, prototnic acid doping is predominating, whereas rare earth ion complexation is predominating when pH>1. Moreover, polyanitine doped wih rare earth chloride exhibits better thermal stability than that doped with hydrochloric acid.

Key words: dope, polyaniline, rare earth chloride, identification
