【Abstract】 Polyindoles were prepared by sodium polystyrene sulfonate(PSS) through oxidation polymerization method at room temperature. The effects of oxidant type, dopant dosage and pH on polyindoles polymerization were investigated. The chemical structure was studied by infrared spectrum(FTIR), ultraviolet spectrum(UV), X-ray diffraction(XRD), Raman spectrum and so on. Scanning electron microscopy(SEM) and nanoparticle size analyzer were used to investigate the morphology and particle size. Four probe tester was used to characterize the electrical conductivity of the materials. The results showed that when using APS/Fe2+ as the oxidation system, the doping ratio of PIn and PSS was 1∶4, pH was 1.68, the obtained polyindole had better performance.更多还原
