摘要：In the current study, fluorene/polypyrrole composite with the core-shell structure has been synthesized by in situ oxidative polymerization of pyrrole in the presence of fluorene. Composite was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. Electrical performance of the composite prepared at various reaction conditions was tested. The composite has the best performance of electrical conductivity when FeCl3-pyrrole molar ratio is equal to 3 and the reaction time is 18 h. It was found that polypyrrole could be formed on the surface of fluorene due to strong pi-pi interactions between the fluorene core and the polypyrrole shell.
