摘要：

The pyrrole-oligomer nanoparticles doped dodecylbenzenesulfonic acid (DBSA) have been fabricated in water-DBSA-isopropyl alcohol-isooctane reverse microemulsion, since DBSA Could play the roles of both surfactant and dopant. We have found the optimum synthetic conditions c by the analysis of factors affecting the yield and conductivity of oligopyrrole. The effect of solubility on the improved properties of DBSA-oligopyrrole in some organic solvents was Studied employing UV-vis-NIR spectroscopy. This indicates that doping and pyrrole-oligomers may improve the poor processibility of PPy. Its environmentally stable properties were characterized by thermogravi metric and differential thermal analysis (TG-DTA). The maximum room temperature conductivity of products is 8.01 S/cm using the four-probe technique. The pyrrole-oligomers have been determined by the analysis of molecular weight measurement, and X-ray photoelectron spectroscopy (XPS) and elemental analysis were employed to investigate the formation of DBSA-oligopyrrole complexes. Correspondingly, the structural properties of DBSA-oligopyrrole were studied by infrared spectroscopy (IR), X-ray diffraction (XRD), transmission electron micrographs (TEM), and scanning electron microscopy (TEM).
