Polyaniline-Doped Poly (Methyl Methacrylate) Microfiber for Methanol Sensing

The main objective of this paper is to investigate the effect of Polyaniline (PANI) as a dopant in the fabrication of a polymer microfiber for sensing methanol. A simple direct drawing technique was employed in the preparation of a Poly (methyl methacrylate) (PMMA) doped with PANI microfiber. The ch...
