Polyaniline nanoskein (PANS), which have polyaniline nanofibers, was developed. PANS was 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 has been shown convertible absorbance characteristics according to surrounding acidic environments, and using these characteristics, the possibility of PANS for sensing of surrounding redox state changes is presented.

开发了具有聚苯胺纳米纤维的聚苯胺纳米丝（PANS）。通过顺序萃取，加热和溶胀工艺配制PANS。已使用X射线光电子能谱，傅里叶变换红外光谱，热重分析和Brunauer-Emmett-Teller分析对PANS的成分进行了分析，结果表明PANS完全由有机材料组成。此外，PANS已显示出根据周围酸性环境可转换的吸光度特性，并使用这些特性，提出了PANS用于感测周围氧化还原状态变化的可能性。
