Source abstract
Abstract
Abstract The development of efficient and quick-response gas sensors for triethylamine (TEA) detection is crucial for human safety and environmental protection. In this study, reduced graphene oxide (rGO)/NiCo2O4 composite films were fabricated by a hydrothermal method to construct flexible gas sensors for the detection of TEA. The rGO/NiCo2O4 sensor demonstrated a linear response to 1–200 ppm TEA, with ultrafast response/recovery times (4/9 s) at 50 ppm as well as excellent stability and sensitivity under cyclic and humidity tests. The response efficiencies were 91.56%, 87.19%, and 85.71% after 60 bending cycles at 30°, 60°, and 90°, respectively, which indicated good flexibility and stability. This study provided a viable strategy for wearable flexible gas sensors in environmental monitoring and health protection.
