In this study, a highly flexible and wearable nitrogen dioxide (NO₂) gas sensor was fabricated based on electrospun poly(vinylidene fluoride) (PVDF)/polyaniline (PANi)/graphitic-carbon nitride (g-C₃N₄) blend nanocomposite (EBNC). g-C₃N₄/PANi nanocomposite (GPC) was synthesized by in situ polymerization technique prior to its incorporation into PVDF nanofibers, which ensured uniformity of dispersion. For the comparison study, PVDF/GPC nanocomposite film was fabricated using doctor blade technique. EBNC sensor exhibited high sensitivity, selectivity, reproducibility along with quick response and complete recovery. Electrospinning and GPC synergistically improved the performance of the EBNC based gas sensor. The superior gas sensing ability along with its low cost and the use of scalable electrospinning technique could make this system a promising one for the detection of gaseous NO₂.

在这项研究中，基于电纺聚偏二氟乙烯（PVDF）/聚苯胺（PANi）/石墨-氮化碳（gC ₃ N ₄）共混纳米复合材料（EBNC）制造了一种高度灵活和耐磨的二氧化氮（NO ₂）气体传感器。）。gC ₃ N ₄ /PANi纳米复合材料(GPC)是通过原位合成的在将其掺入 PVDF 纳米纤维之前采用聚合技术，这确保了分散的均匀性。为了进行比较研究，使用刮刀技术制造了 PVDF/GPC 纳米复合膜。EBNC 传感器表现出高灵敏度、选择性、重现性以及快速响应和完全恢复。静电纺丝和 GPC 协同提高了基于 EBNC 的气体传感器的性能。优越的气体传感能力以及其低成本和可扩展静电纺丝技术的使用使该系统成为检测气态NO ₂的有前途的系统。
