Year: 2023
Type: conference-paper
Abstract: : In the current study, glass substrates were coated with Poly Vinyl Alcohol (PVA) nanofibers that were electrospun. The solution was electrospun at 20 KV while it was still warm using various concentrations of AgNO3 (1%, 2%, and 3% (wt.). The samples collected on the collectors were subjected to scanning electron microscopy (SEM) analysis and X-ray diffraction (XRD) analysis. The typical fiber diameter ranged from 100 nm to 250 nm. The PVA matrix successfully accommodates the Ag particles. PVA/ (1%,2%, and 3%) AgNO3 thin films have also been evaluated as gas sensors for (NO2) at various temperatures, including (120°C, 160°C, and 200°C). Doping is known to increase gas sensitivity. The results of sensing in these films are better than that of other similar materials and suggest that they can be used as high temperature sensors
