Description
Summary:Nanofiberous sensor for ammonia gas is fabricated by electrospinning the composite of poly(diphenylamine), PDPA, with poly(methyl methacrylate), PMMA onto the patterned interdigit electrode. Interconnected fibrous morphology is evident for the electrospun membrane. Functional group and high active surface area of fibrous membrane help the device to have good reproducibility and to detect the lower concentration of ammonia. The sensing capability of device is studied by monitoring the changes in resistance with different concentration of ammonia. The resistance changes shows linearity in range of 10 ppm to 300. The mechanism behind the sensing characteristic is studied using UV-Visible spectroscopy.
