Polyaniline Nanoskein: Synthetic Method, Characterization, and Redox Sensing

Abstract Polyaniline nanoskein (PANS), which have polyaniline nanofibers, is developed. PANS is formulated via sequential extracting, heating, and swelling processes. The compositions of PANS have been analyzed using X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and Brunauer-Emmett-Teller analysis, and the results of which indicate that PANS is composed of solely organic materials. Moreover, PANS have been shown convertible absorbance characteristics according to surrounding acidic environments, and using these characteristics, the possibility of PANS for sensing of surrounding redox states changes is presented.
