Summary

Ammonia gas is a highly toxic, flammable, and dangerous that can cause severe damage to human health, including eye and skin irritation, respiratory system irritation, lung damage, edema, and, in extreme cases, death. The use of sensors is crucial for the protection of worker health and safety and the environment since the early detection of gas presence can allow for the implementation of safety measures to prevent exposure, reduce risks, and minimize health damage. In this study, conductive polypyrrole (PPy) nanofibers in an insulating polymer matrix (PMMA), produced by the electrospinning technique, were used for ammonia (NH3) gas sensors. The electrospinning technique allows for the production of nanofibers with a surface area up to 10³ times greater than microfibers [1], with the possibility of having a porous structure and electrical conductivity [2], which increases the sensitivity and response [3]. Different concentrations of PPy were added to PMMA, and the nanofibers were characterized by optical microscopy (OM), scanning electron microscopy (SEM), infrared spectroscopy (FTIR), and direct DC electrical measurements. The SEM analysis showed the formation of nanofibers with different diameters and an increase in conductivity with the addition of PPy in PMMA, confirmed by DC electrical measurements. These nanofibers presented promising characteristics to be used as a sensitive layer in an ammonia (NH3) gas sensor due to properties such as low response time and electrical conductivity.
