Abstract

As part of a program focused on the development of selective conducting polymer gas sensors, we have investigated the behavior of polyaniline-platinum oxide chemoresistors in the presence of combustible gases such as hydrogen, methane, ethylene, acetylene and carbon monoxide. In this paper we report on results obtained using a polyaniline-platinum oxide sensor. By hydrogen atmosphere preconditioning, we were able to increase the selectivity and sensitivity of the sensors for hydrogen in air at concentrations between 1000 and 5400 parts per million (ppm).
