Polypyrrole(PPy)is prepared through chemical oxidation method.The influences of oxidants(FeCl3 and(NH4)2S2O3),reaction temperature(ice bath temperature and room temperature)and reaction time(6 h and 12 h)on the synthesis of conductive polypyrrole are studied,and the reaction conditions are optimized.The influences of different concentrations of surfactants SDS doping on the structure and morphology of pyrrole monomer polymerization are investigated emphatically.The product samples are analyzed by means of scanning electron microscope(SEM),Fourier transform infrared spectrometer(FT-IR),X-ray photoelectron spectroscopy(XPS),thermogravimetric analysis(TGA),specific surface area test(BET)and conductivity test.The optimum process conditions for the synthesis of conductive polypyrrole are determined as follows:FeCl3 is used as oxidant,and reaction has performed in ice bath for 6 h.The conductivity of the product can reach 0.076 9 S·cm-1.An appropriate addition of SDS changes the micro-morphology of the product sample,which is beneficial to improve the thermal stability and conductivity of polypyrrole.
