Abstract
The fabrication and sensor properties of polyaniline-platinum oxide chemore sistors in the presence of combustible gases such as hydrogen, methane, eth ylene, acetylene and carbon monoxide is reported. Prior conditioning of the sensors in a hydrogen atmosphere resulted in increased selectivity and sen sitivity for hydrogen in air at concentrations between 1000 and 5400 ppm. T he conditioned sensors showed negligible response to hydrocarbons and carbo n monoxide.
