Dichloroacetic acid was taken up as an acid with low degree of ionization which does not eat ITO away, and was used to study about the doping characteristics of polyaniline films. The degree of electrolytic dissociation of sulfuric acid is high, and it gives high electric conductivity to polyaniline by the doping. Electric conductivity becomes high with doping by dichloroacetic acid, and the value matches doping by sulfuric acid in high concentration. However, at low concentration, electric conductivity becomes low fairly with dichloroacetic acid doping compared with sulfuric acid. The anion of dichloroacetic acid is large compared with it of sulfuric acid, and what cannot permeate to a polyaniline film easily is considered to be the cause. Moreover, I-V characteristics of an ITO/dichloroacetic-acid-doped pAn/Metal element were studied. In Au, a very stable OMU nature was formed. In In and Sn, some potential barriers were formed in pAn/In and the pAn/Sn interface and the unique I-V characteristic was shown.
