摘要： Graphite oxide (GO)/ordered polyaniline (PANI) composites have been prepared through an in situ polymerization. TEM, XRD, FTIR and XPS analyses show that the PANI grew along the surface of exfoliated GO as a template to form a more ordered structure with high crystal-Unity during polymerization. Compared with pure PANI, both higher electrical conductivity and higher Seebeck coefficient of GO/PANI composites result from the increased carrier mobility, which is confirmed by Hall measurement. Strong interactions exist between graphene oxide and PANI, including electrostatic forces, hydrogen bonding and π-π stacking. There is no significant difference in thermal conductivity between GO/PANI composites and PANI. The maximum electrical conductivity and Seebeck coefficient of the composites reach 751S m~(-1) and 28.31 μV K~(-1), respectively. The maximum thermoelectric figure of merit is up to 4.86 x 10~(-4), 2 orders of magnitude higher than that of pure PANI.
