MULTI-WALLED CARBON NANOTUBE NETWORK FOR GAS SENSING APPLICATION
Abstract
In this study, the multi-walled carbon nanotube (mwCNT) network is suggested as a sensitive element of a gas sensor. An increase in the electrical resistance and capacitance of the sensor elements due to the adsorption of ammonia, acetone and ethanol molecules was found. The concentration dependences of the sensing ability and dynamic characteristics of resistive and capacitive type sensors were studied to evaluate the sensor properties of the mwCNTs. The response time of the gas sensor based on the mwCNT network to changing concentrations of ammonia, acetone, and ethanol molecules does not exceed one minute at room temperature. The obtained results expand the perspective of the mwCNTs application in sensor devices.
Keywords: multi-walled carbon nanotubes, gas sensors, sensing ability, response time.
