Thin films of polyaniline have been deposited by spinning, evaporation
and by the Langmuir-Blodgett technique. The films are shown to possess
slightly different in-plane electrical conductivities, reflecting
differences in their chemical structure and layer morphology. The
conductivity is found to depend on the gas ambient. All types of
polyaniline films are sensitive to H2S and NOx at concentrations down
to 4 ppm. However, only spun and evaporated films are responsive to SO2.
