Gas sensors based on conductive polymer film have advantages such as material variety, solution process, flexibility, and lightweight. However, the signal of the organic gas sensor is lower than the metal oxide gas sensors due to its poor charge carrier transport. To improve the sensitivity of the organic gas sensor, blending porous materials can be effective to enhance the interaction between gas molecules and the active layer. Herein, we fabricated the organic gas sensor with enhanced sensing abilities for the NO2 gas by blending the nitrided zeolite with a conductive polymer. Zeolites were nitrided in 3 different temperatures to control the nitrogen content in the particle, and the effect of the nitrided zeolite on the sensing properties was investigated under various NO2 concentrations. The microporous structure of zeolite provides the pathway for gas molecules to penetrate the channel region and nitrogen in zeolite particles has strong interaction with the gas analyte. |
