Gadolinium Chloride (GdCl 3 ) has been employed as dopant to synthesize conductive polyaniline (PANI) using chemical method. The resulting products were characterized using infrared spectroscopy, UV–vis spectra, scanning electron microscope, differential thermal analyzer, and X‐ray diffraction. It was found that Gd 3+ can interact with PANI chains and induce changes on the properties of PANI. The addition of GdCl 3 could greatly increase electrical conductivity and crystalline degree of PANI. Changes in UV–vis and FTIR spectra show that there exists interaction between gadolinium ions and PANI chain. The effect of different proportions of ammonium persulfate on the properties of PANI was also discussed. When the molar ratios of GdCl 3 to aniline is 2 : 1 and ammonium persulfate to aniline is 1 : 1, the more uniform and regular PANI nanofiber can be prepared. © 2006 Wiley Periodicals, Inc.
