摘要

本研究通过电纺丝和原位聚合合成了热塑性聚氨酯/微孔碳纳米管/PANI/GQDs（TMPG）复合材料，开发出一种可在室温（RT）下可靠检测 NH3 的柔性传感器。在相对湿度为 60% 时，TMPG 传感器对 10 ppm NH3 的响应为 51.3%，这归功于独特的三维（3D）多孔结构和增强的 PANI 质子化。此外，该传感器还具有良好的选择性和可重复性，即使在经过 1000 次弯曲循环后仍表现良好。它还被有效地应用于羊肉新鲜度监测和可穿戴式 NH3 安全报警。这项研究为设计用于柔性可穿戴电子设备的高性能 NH3 气体检测平台提供了契机。

Adaptable Ammonia Detection With QDs-Sensitized Polyaniline Mat: A Flexible Gas Sensor for Diverse Applications

In this study, TPU/MCNTs/PANI/GQDs (TMPG) composites were synthesized through electrospinning and in-situ polymerization, developing a flexible sensor for reliable NH3 detection at room temperature (RT). At 60% relative humidity, the TMPG sensor shows a response of 51.3% to 10 ppm NH3, attributed to unique three-dimensional (3D) porous structure and enhanced PANI protonation. Moreover, the sensor exhibits good selectivity and repeatability, performing well even after 1000 bending cycles. It has also been effectively applied in monitoring mutton freshness and wearable NH3 safety alarming. This research provides an opportunity for designing a high-performance NH3 gas detection platform for flexible wearable electronics.
