| 中文摘要 | We report a comparative study among four kinds of polyaniline (PANI) synthesized with four different kinds of acids, under the same conditions for synthesis; PANI-HCl, PANI-H2SO4, PANI-H3PO4 and PANI-C4H6O6. We measured the temperature dependence of the dc conductivity sigma(dc)(T) and the magnetic susceptibility chi(tot)(T) The room-temperature conductivity of HCl and H2SO4-polyaniline was 5-8 times higher than that of H3PO4 and C4H6O6-polyaniline, in which the values of 18.1, 16.8, 3.8 and 1.85 S/cm were found, respectively. The best fit for our de conductivity data was obtained using the quasi-one-dimensional variable-range hopping (QID VRH) model between nearest neighbors. Polyaniline reported in this paper leads to a high magnetic susceptibility chi(tot) (at T = 295 K) of 10(-4) emu/mol.2rings. This is one or two orders of magnitude higher than those reported earlier for polyaniline. Data on sigma(dc)(T) and chi(tot)(T) are also discussed. |
