Abstract
A flexible nitrogen dioxide sensor based on tungsten trioxide nanoparticles-loaded multi-walled carbon nanotubes-reduced graphene oxide (WO3 NPs-loaded MWCNTs-RGO) hybrid on a polyimide/polyethylene terephthalate substrate. A viscous gel of the hybrid materials can be prepared by the assistance of α-terpineol. The fabricated sensor shows excellent sensing performance toward NO2 which may have a maximum response of 17% (to 5 ppm), a limit of detection of 1 ppm, and relatively short response/recovery time (7/15 min). The sensor may exhibit excellent mechanical flexibility and sensing properties at room temperature without any significant performance degradation even at a curvature angle of 90° and after 106 times of bending/relaxing processes. Low cost, light weight and mechanical robustness of the proposed WO3 NPs-MWCNTs-RGO hybrid based sensor can be a promising element for the development of flexible NO2 gas sensors having higher performance.
