摘      要：Polypyrrole (PPy) was synthesized under dry nitrogen atmosphere by chemical polymerization. The oxidant agent, ferric chloride, was mixed with several types of solvents, such as hydrochloric acid, deionized water, and acetonitrile, before the monomer pyrrole was added. The resultant precipitate was filtered and rinsed with methanol and ethanol several times and dried in vacuum oven at 40 °C for over 12 h. Conductivity tests, x-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy were carried out to investigate the structure and morphology of PPy. The conductivity of the prepared samples was studied in the frequency range 100 Hz to 1 MHz over the temperature range 253-393 K. The degree of surface density of PPy powder was directly related to its dependence on solvents, which can be represented via the following: H2O ACN HCl.
