POLYANILINE THIN-FILMS FOR GAS-SENSING

Agbor, NE; Petty, MC; Monkman, AP

Abstract

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.
