| The experiment of the paper selected chemical method and the preparation of doped polyaniline was fulfilled by using doped reagent of toluene-p-sulfonic acid (p-TSA) and oxidant of ammonium superphosphate. Meanwhile, a new synthetic method of PANI/ND2O3 was mentioned, and the property of surface active agent of p-TSA was utilized. Firstly the Nd2O3 was ultrasonic distributed in p-TSA aqueous solution. Secondly we selected chemical method; the, preparation was the same as that of PANI. Finally, we obtained PANI/Nd2O3 composite materials.The structure and properties of hybrid materials were taken by means of SEM, FT-IR, and so on. The electrical conductivity of PANI/Nd2O3 was measured by four-probe method. We studied the influence of the electrical conductivity under different experimental conditions, including reaction times and temperatures, and different molding pressures. In the FT-IR spectrum of PANI/Nd2O3, the special picks of PANI were obvious, but there were blue shifts of different degrees, which indicated the addition of oxid had some influence on the structure of PANI and there existed some chemical linkage between them. The addition of Nd2O3 makes the conductivity of PANI weak. The conductivity reduced along with the rise of the reaction temperature and increased along with the rise of molding pressures. The conductivity tended to be stable when the molding pressure was over 10 MPa and it reached the top when the reaction time was 16 hours, later it became gradually weak with the time increased.Electrode film of PANI/Nd2O3 nanocomposite was prepared onto Pt electrode by situ-polymerization method. The electrochemical catalyze active of the electrode (PANI/Nd2O3/Pt) to the oxidization of HCOOH was studied by means of cyclic voltammetry (CV). The CV results indicated that the electrochemical catalyze active of PANI/Nd2O3/Pt electrode was existent to the oxidization reaction of HCOOH solution, which was superior to Pt electrode and PANI/Pt electrode. |
