Abstract: Acid-doped polyaniline (PANI) nanofibers have been successfully synthesized by interfacial polymerization and characterized by TEM, FT-IR and UV-vis spectra and thermal analysis. The TEM results show that the type of dopant acid: acetic, phosphoric, hydrochloric and perchloric acids, and the concentrations of aniline monomer and acid affect the morphology and diameter of the nanofibers. The diameters of the nanofibers are in the range of 30-50 nm, which increase with the increase in acid strength. The electrical conductivity of nanofibers varies in the order: HAC-PANI<H₃PO₄-PANI<HClO₄-PANI< HCl-PANI, which is closely related to the acid type and the size of its negative ion. Thermal stability of acid-doped PANI is different from that of EB PANI, which is attributed to the strong interaction between PANI and doped acid.
