Summary: Nanoscaled polyaniline (PANI) fibers with 17–30 nm in diameter were successfully prepared by oxidation polymerization using ferric hydrochloride (FeCl 3 · 6H 2 O) as an oxidant in the presence of p ‐toluenesulfonic acid ( p ‐TSA), β ‐naphthalenesulfonic acid ( β ‐NSA), and camphorsulfonic acid (CSA) as the dopants. The resulting nanofibers show smaller diameter, higher crystallinity and conductivity (10 −1 S · cm −1 ) compared with the nanofibers oxidized by ammonium persulfate (APS), which may be due to the lower oxidation/reduction potential of FeCl 3 .SEM images of the PANI nanofibers prepared by oxidation polymerization using ferric hydrochloride as an oxidant.
