【 摘 要 】

(PANI/Fe3O4)-Ag films have been successfully synthesized on a glass substrate. In this study, PANI functioned as a matrix, Ag as a catalyst enhancing the conductivity of PANI, and Fe3O4as the influence of magnetic properties. (PANI/Fe3O4)-Ag was synthesized by a combination of chemical polymerization method to introduce Ag doping into PANI, and coprecipitation method of Fe3O4. The samples were characterized by using FTIR, X-RD, SEM, EDAX, 4-probe electrical conductivity under the employing of magnetic fields, and under the influence of light intensity. It was shown that there was a Fe2O3phase as the consequence of Fe3O4oxidized as AgNO3protonation on the ultrasonication treatment. introducing Fe3O4into (PANI/Fe3O4)-Ag film, increase the surface density, but reduce the electrical conductivity. The increasing of magnetic field might also reduce the conductivity of (PANI/Fe3O4)-Ag. Further, We also obtained that the increasing of light intensity employed to the samples enhances the electrical conductivity. The electrical conductivity of (PANI/Fe3O4)-Ag can be tuned by controlling the Fe3O4, magnetic field, as well as the light intensity.
