Abstract

This paper reports the fabrication of a novel resistive-type relative humidity sensor based on plasmafunctionalized MWCNT/Polyimide composite films. Therelative humidity sensors shows a good linearity of 1.10 over a wide humidity range, with the sensitivity of 60O/%RH and response time of 10 min. The resistance increase with water adsorption of composite films with high MWCNTconcentration is explained on the basis of charge transfer between the adsorbed water molecules and the CNTs.
