Partially crystalline structure of doped polypyrrole and polyaniline is investigated by the X-ray diffraction experiment and compared with the results from transport measurements. The increase of crystallinity along the direction of polymer chain in pyrrole-hexafluorophosphate (PPy-PF 6 ) film indicates that intrachain disorder plays a critical role in transport in the metallic regime of the...
The electrochemical synthetic conditions to prepare high quality polypyrrole films of high electrical conductivity ( > 300 S/cm) are investigated. The low temperature transport properties of polypyrrole-hexafluorophosphate (PPy-PF 6 ) films are optimized by the control of polymerization conditions such as temperature (T p ), current density (J p ), and the total charge passed...
