Abstract: Disclosed is a colorimetric gas sensor using a complex polymer nanofiber structure for yarn-based gas indication, in which ionic liquids as effective gas adsorbents and color change dyes having varying colors have been functionalized in a nanofiber and a method of fabricating the same. In the fabrication method, after the ionic liquids and color change dyes are mixed with a polymer solution in which high-temperature stirring and quenching processes are accompanied to prepare fine crystals of color change dyes. Accordingly, the dual-electro-spinning process is conducted to produce the nanofiber yarn scaffold on which ionic liquids and color change dyes are finely functionalized.
