Recently, there has been a growing interest in improving the gas sensors performance of organic materials. Our research aimed to improve the gas sensing performance of the sensors by blending polythiophene (P3HT) and Mg-DML-x zeolite (x = 100~180 °C). Mg-DML-x was chosen due to its abundant hydroxyl groups and magnesium oxide, which act as active sites for oxidizing gases. We expected that the Mg-DML-x would boost the responsivity to these oxidizing gases. The P3HT films blended with Mg-DML-x showed higher NO2 responsivity compared to the pristine film, and the P3HT film with Mg-DML-160 exhibited the highest responsivity, response and recovery rates. However, with more than 50 wt% of zeolite content, the gas sensing performance started to decrease due to aggregation of Mg-DML-x at higher concentrations. These results indicate that optimizing the dimension and amount of zeolite can significantly enhance the gas sensing performance, enabling them to more effectively detect harmful gases.
