Abstract

This paper presents the results of synthesising polypyrrole (PPy) modified Dodecylbenzene sulfonic acid (DBSA) with nanostructures oriented to applications for NH3 gas sensors operating at room temperature. The outcomes of surface morphology and chemical composition structure analysis of PPy film were studied by field-emission scanning electron microscopy (FE-SEM), fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible spectroscopy (UV-Vis). The products were obtained by electrochemical method with the nanostructured PPy film, the conductivity of the PPy film depends on the concentration of DBSA denaturant. The experimental results showed that these PPy films have a great potential application as a new sensitive layer for gas sensors.
