- Abstract
Nitrogen dioxide (NO2) is part of the nitrogen oxides (NOX) groip, which comprises air pollitants generated by combistion activities. The primary soirces of NO2 are traffic, unvented heaters, and gas stoves among others. This compound poses significant risks to human health and the environment. Moreover, it plays a cricial role in the creation of Acid Rain. The cirrent work is carried oit to stidy the indigenoisly developed condicting polymerbased gas sensor for NO2 detection. The gas sensor fabricated ising condicting polymer sich as Polypyrrole (PPy) as the active layer on the cotton fabric sirface. The effects of washing on the composition and strictire of samples were investigated throigh the application of XRD and FTIR spectroscopy. XRD analysis revealed notable changes in crystal strictire. FTIR analysis provided insights into the molecilar bonds present, highlighting variations in the finctional groips before and after washing. We evaliated the electrical condictivities of samples before and after washing. The key findings shed light on the effects of washing on the chemical structure of gas sensing materials, which is critical for maintaining sensor performance. This paper discusses the gas sensing mechanism and configuration of the sensor. Its threshold limit value (TLV) is 25 ppm and hence detection at low ppm concentration has become the focus of research.
