| Outline of Final Research Achievements |
Polyaniline films were formed on an Fe substrate using the oxidative electropolymerization technique at 288 K. Although the polyaniline films were partially formed in solutions of pH 2-4, the films completely formed and their surfaces became smooth when deposited in solutions of pH 7-10. Polyaniline films with smooth surfaces and good corrosion resistance were obtained at 8-30 A・m－2, whereas the films obtained at current densities greater than 50 A・m－2 exhibited non-uniform surface morphologies and poor corrosion resistance. Films obtained at anode potentials of 0.4 V and 0.8 V were not formed completely, and the films formed at an anode potential of 2.0 V exhibited very rough surfaces. In the case of polyaniline films formed in an electrolyte solution containing both p-toluenesulfonic acid and oxalic acid, the Fe exhibited improved corrosion resistance, and the films exhibited good adhesion to the Fe substrate.
