Gas sensors based on organic field-effect transistors have attracted interest due to their advantages such as low cost, flexibility, material variety, and lightweight. However, the signal of the organic gas sensor is lower than the inorganic gas sensors due to its poor interaction with the target gas molecule. To enhance the interaction between gas molecules and the active layer organic gas sensor, blending porous materials such as zeolite can be effective. In this work, we fabricated the organic gas sensor with improved sensing abilities to the NO2 gas by blending the nitrided zeolite (N-ZSM-5) with a conductive polymer. The blend film showed enhanced gas sensing properties since the nitrogen in zeolite particles had a strong interaction with the gas molecule and the microporous structure of zeolite provides the pathway for gas molecules to penetrate the channel region. These results provide the application of organic gas sensors based on zeolite/conductive polymer blend films. |
