Characterization of electronically conducting polypyrrole based composite materials

Structure and conductivities (heat and electric) of polypyrrole composites, synthetized chemically and impregnated by silver solutions, have been studied. The silver content and the physical properties of the composite materials compressed into tablets were determined. The presence of silver in the concentration range below 5% had minimal effect on the electric and heat conductances of polyprrole. XRD measurements showed that the form of the incorporated silver was Ag metal or AgCl depending on the anion present in the polymerization solution. The distribution of the silver particles obtained from TEM measurements proved the presence of nanosized metal component.
