The fabrication and sensor properties of polyaniline-platinum oxide chemoresistors in the presence of combustible gases such as hydrogen, methane, ethylene, acetylene and carbon monoxide is reported. Prior conditioning of the sensors in a hydrogen atmosphere resulted in increased selectivity and sensitivity for hydrogen in air at concentrations between 1000 and 5400 ppm. The conditioned sensors showed negligible response to hydrocarbons and carbon monoxide.
