Abstract

In this paper, the authors presented some research results on the various surface morphologies of polyaniline (PANi) film, directly synthesised on Pt/SiO2 interdigitated microelectrode area by electrochemical method. The outcomes of surface morphology and chemical composition structure analysis of PANi film were studied by Field-emission scanning electron microscopy (FE-SEM) and Fourier-transform infrared (FT-IR), respectively. The PANi film was fabricated with the nanowires (NWs) form with their diameter from 50÷100 nm. The length of several micrometers depends on aniline concentration and synthesis condition. The obtained consequences demonstrated that the PANi - NWs are fully potential objects for the detection of NH3 gas at room temperature.
