Abstract

The multi-walled carbon nanotubes combined with four polymers respectively were used as a sensitive layer of in the monolithically integrated gas sensor array. The multi-walled carbon nanotubes in the gas sensor array were added using a dip coating, and the corresponding polymer was added to different sensors in the array by spraying coating. The sensor array demonstrated the ability for detection and discrimination of different volatile organic compunds (VOCs). The adsorption characteristics of VOCs vary with different kinds of polymers. The adsorption of VOCs affected the conductive network in the sensitive layer and caused its resistance change. By measuring the change in resistance of these sensors as the output signal of the sensor array, the experimental results demonstrated the potential of using such devices for VOCs detection and analysis applications.
