Abstract

We have developed a new method for preparing conducting polyaniline films and investigated their chemical and physical properties by means of UV-Vis., FT-IR, and dc conductivity measurements. Conducting polyaniline films are prepared by casting directly a lithium salt containing non-conducting polyaniline solution. The dried films show high dc conductivity even without further treatment with HCl. Effects of lithium salts, such as LiBF 4, LiPF 6, and LiClO 4, and their concentrations on dc conductivity are examined. The dc conductivity of Pani-LiBF 4 film is found to be better than those of Pani-LiPF 6 and Pani-LiClO 4 films. The dc conductivity increases with lithium salt concentration ranging from 0.1M to 0.025M, and exhibits maximum value of ∼10 -1 S/cm when 0.1M LiBF 4 is doped.
