Structural and Charge Transport Mechanism of Polyacetylene Composites

Polyacetylene was synthesized by using Ziegler-Natta catalyst with chemical polymerization method and doped it with 10% iodine and 10% bromine to prepared the composites. The samples were characterized by XRD, SEM and temperature dependent DC electrical conductivity. The XRD pattern of doped polyacetylene displayed that the crystallinity was improved. The SEM morphology of doped polyacetylene demonstrated that granularity was increased. The calculated electrical conductivity shows the low electric conductivity of pure polyacetylene but when we doped polyacetylene with iodine and bromine the electrical conductivity was improved. This study explored that the improvement in the electrical conductivity which may confirm the doped polyacetylene behave as semiconductor and can by helpful for the potential application of devices and related fields.
