Abstract

The invention discloses a nanometer polyaniline material with appearance hereditary potency and an electrochemistry preparation method thereof. The method comprises the following steps: aniline and doping acid I are added into water, stirred to form doping acid I solution of the aniline; in a three electrode system, the doping acid I solution of the aniline is added into an electrolytic cell; theelectrochemical synthesis is carried out on a working electrode for obtaining the polyaniline material with nanometer structure doped with the doping acid I; after the electrochemical synthesis is finished, a polyaniline modified electrode doped with doping acid I is obtained; the modified electrode is used as the working electrode, put into water solution containing doping acid II, electrolyzed to a cyclic voltammetry graph by using cyclic voltammetry and stable to obtain the polyaniline material doped with doping acid II, the appearance of which is same to the polyaniline nanometer structure doped with the doping acid I obtained in the second step. The polyaniline material obtained in the invention only has difference in the chemical composition of doping ions and does not change the microscopic morphology of polyaniline. The appearance hereditary has important using value.
