摘要: The dielectric spectroscopy of conducting polyaniline polymers (PANI) in the form emeraldine base and salt was carried out temperature range 30 to 80°C frequency 1 Hz 1 MHz. imaginary part impedance (Z″) versus exhibits a relaxation peak, positions peaks are shifted toward lower frequencies for concentrations below 0.1 M, whereas higher above 0.1 M. PANI samples were protonated (doped) externally with various aqueous sulfuric acid 0.05 0.2 molar. thermal behavior undoped doped has been analyzed, using gravimetric analysis differential scanning calorimetry techniques, reveal that transition observed 0.1 a.c. conductivity measurements insulator metal these acid...
