Abstract
This thesis was devoted to study the morphology, electrical conductivity and magnetoconductivity at low tamperatures of some different conducting polymers,such as, polyacetylene and polypyrrole. polyacetylene samples were prepared by using the shirakawa modified method, whereas, polypyrrole samples were prepared by using the elecrtochemical method on PT electrode in one compartment cell containing two electrodes at different preparation conditions.
