Characterisation of PPY/CECl3 Composite Synthesized By Simple Chemical Polymerization Method

Organic conducting polymers and their composites have become increasingly important for technical applications and the use of organic or inorganic fillers (dopants or composites) can prepare a new polymeric material with interesting combinations of physical mechanical and electrical properties. Among all organic conducting polymers polypyrrole is one of the most promising material for multifunctionalised applications.This contribution deals with structural modification of polypyrrole by doping it with rare earth metal salt CeCl3 to study its dynamic physical, mechanical and electrical conducting properties. The conducting PPy / CeCl3 composite was synthesized by chemical oxidative polymerization method in aqueous media with ammonium peroxydisulphate as an oxidant at low temperature.The monomer to oxidant ratio was 1:1M. The concentration of CeCl3 was varied from 0.01-0.2. All the composite samples were characterized through FTIR/NMR/Mass analysis. IR result show that interaction exist between PPy and CeCl3
