Summary:The synthesis of NGQDs was carried out via a microwave-assisted hydrothermal method where citric acid and urea were used as carbon and nitrogen sources, respectively. Uniformly distributed and spherical NGQDs were achieved after a 4 minutes reaction time and these dots were further loaded onto PANI/PAN to produce NGQDs/PANI/PAN composite via in-situ polymerization and electrospinning. Optimized electrospun composite fibers were characterized and later used for alcohol vapor sensing.
