Abstract
Free-standing films were obtained by solution casting of polyaniline. Conductivities of the films were measured as functions of the protonat ion state (doped in pH 0.5 approximately 6 H2SO4 solution) and heating temperature. The conductivity increased with decreasing pH and heatin g temperature and is correlated with the background absorbance at high wavenumbers in the IR spectrum. The conductivity could estimated from the observed background peak in the IR spectrum.
