摘要: Polypyrrole/carbon (PPy/C) composites have been synthesized using varying concentration of p-toluenesulfonate (pTS) dopant by surface initiated in-situ chemical oxidative polymerization. The synthesis and influence pTS on the structure PPy/C are confirmed Fourier transform infrared studies morphological features examined scanning electron microscopy. X-ray photoelectron spectroscopy, employed to examine composition doping level these composites, confirms anionic into polymer backbone. Electron spin resonance measurement has carried out samples identify nature charge carriers their at different levels. dc electrical conductivity measured in temperature range ∼10–305 K. observed results analyzed framework existing theoretical models. Different Mott's parameters, such as characteristic (T0), density stat...
