Both the poly pyrrole film and the hydrous manganese oxide,s capacitors was examined reversibility, agening behavior and capacitance value. The purpose of this work finds better preparation conditions to plate poly pyrrole and hydrous manganese oxide. This work uses cycle voltammetry to prepare electrode of poly pyrrole film. When poly pyrrole with iron nano-particle can promote capacitance value from as 351.61F/g, with the btter preparation condition is scan cycle number of 100 cycle numbers, the scan rate is 20mV/s, and the UV value of iron nano-particle at UV value is 1. Moreover, the hydrous manganese oxide with iron nano-particle can promote the best capacitance value as 413.26 F/g, and the better condition is scan cycle number of 30 cycle numbers, the scan rate is 20mV/s, and the UV value of iron nano-particle at UV value is 0.2. In addition, the poly pyrrole and hydrous manganese oxide with iron nano-particle can improve reversibility and duability of these two kinds of electrodes. In the SEM results, we observe the morphology of poly pyrrole film and hydrous manganese oxide were smooth and with using the iron nanoparticles sol. Those smooth surfaces of the poly pyrrole film and hydrous manganese oxide can proof that the high capacitor value was contributed by active sites form the XRD results, the iron nano-particle,s was examined as the FeO(OH) crystal in the poly pyrrole electrode, but we can’t find any metal crystal in the hydrous manganese oxide. The intensity of the graphite diffraction peak is decreased with the increase of the concentration iron nano-particle. The decrease of graphite depicts that the deposition rate of hydrous manganese oxide is increased by using the iron nano-particle.
