Meta-Analysis of the Effect of Inorganic Micro/Nanomaterial Additives on Polyaniline Based NH₃ Gas Sensor Performance

“…The maximum sensing response in the given range was 930% at 100 ppm NH3 gas concentration. The sensitivity and low LOD of PAni/CuO@3D-NGF based sensor were highly fascinating when compared with pure PAni that have 26% response and are unable to detect NH3 gas concentration below 1 ppm [22]. These high-performance enhancements were attained due to the following reason as reported by the research group;…”

“…The lower LOD of this nanohybrid sensor was 0.003 ppm. The extremely high response and ultra-low detection limit of the PAni/WO3 nanohybrid sensor towards NH3 gas as compared to pure PAni which has only 26% response to 100 ppm NH3 gas concentration, and lower base LOD is 1 ppm while for PAni/WO3 LOD found as 0.003 ppm, which highlights this polymer composite material as one of the best materials for sensor application [21,22].…”

“…The possible roles of WO3 in the nanohybrid material were forming a structure suitable for the smooth flow of NH3 gas, facilitating fast electron transport, and initiating adsorption/desorption cycles in the sensing mechanism. Tabar et al fabricated an innovative NH3 gas sensor from PAni/cupric oxide nanoparticles on 3-D nitrogen-doped graphene (NGF) based frameworks (PAni/CuO@3D-NGF) using in situ polymerization [22]. It was reported in their study that the lower LOD of this sensor was 0.05 ppm concentration of NH3 gas.…”
