Abstract

Polypyrrole/exfoliated graphite composite was synthesized by expandable graphite, pyrrole and sodium dodecylbenzenesulfonate, via a new method of ultrasonic assistance—thermal expansion at low temperature. At the same time, the composite was characterized by scanning electron microscope and Fourier Transform infrared spectroscopy. The results exhibited that expandable graphite wrapped by polypyrrole could be prepared in the ultrasonic assistance and the composite synthesized in the thermal expansion. The results also showed that the composite provided with the wormlike morphology and the structure of exfoliated graphite wrapped by polypyrrole and polypyrrole would be oxidized while the expansion temperature was higher than at 350°C. This shows that the method not only is credible but also the especial morphology and structure indicate applications in some fields.
