Abstract One of the frontier research areas in field gas sensing is high-performance room temperature-based novel materials, and new family low-cost eco-friendly carbon nanomaterials with a unique structure has attracted significant attention. In this work, we propose flexible temperature ammonia sensor based on nitrogen-doped nano-onions/polypyrrole (NCNO-PPy) composite material mounted membrane substrate was synthesized by combining hydrothermal in-situ chemical polymerization methods. The proposed revealed high performance when employed as for detection at temperature. NCNO-PPy exhibited 17.32% response 100 ppm concentration low time 26 s. displays selectivity, good repeatability, long-term durability 1 lower limit. also demonstrated remarkable mechanical robustness under extreme bending conditions, i.e., up to 90° angle 500 cycles. This enhanced can be related potential bonding synergistic interaction between CNOs PPy, formation defects from nitrogen doping, presence reactive sites surface composites. Additionally, computational study performed optimized nanocomposite both without NH 3 interaction. A deeper understanding phenomena computation several electronic characteristics, such band gap, electron affinity, ionization potential, composite.
