摘要： Flexible gas sensors are gaining interest for real-time volatile gas monitoring. A natural rubber (NR)/MXene nanocomposite sensor is developed. Among the six selected target volatile gases, the composite sensor exhibited a strong response value (82% toward 100 ppm NH3) with the fastest response/recovery time (12.3 s/15.5 s) to NH3. The sensitivity showed a clear dependence of gases, suggesting a good selectivity to varying gases. Ti3C2Tx MXene gas sensors exhibited a very low limit of detection of 50-100 ppb for volatile organic compounds (VOCs) at room temperature. In addition, the NR/MXene sensor allows detection of the mixture of ammonia (NH3), dimethyl sulfoxide (DMSO), and acetone (C3H6O) and it shows good response depending on the total concentration of VOC gases. Furthermore, the flexible nanocomposite sensor exhibits stable sensing performance at different bending states (0-120 degrees) and shows 20-day atmospheric stability. This sensor's ability extends to alcohol breath analysis, useful for drunk driving detection. This work paves the way to the possibility of using robust MXene-based toward practical realization of electronic devices. A nanocomposite flexible gas sensor is developed by simply drop casting natural rubber/MXene mixture onto interdigitated electrodes. This advanced sensor shows remarkable selectivity and sensitivity toward six distinct volatile gases. Additional durability and stability study represents a significant advancement in the field of flexible electronics, offering promising prospects for real-world applications. image
