Abstract

In this paper, we have developed a simple, facile, and efficient approach to synthesize polyaniline/Mn3O4 (PANI/Mn3O4) nanocomposites using aniline as a reducer in the presence of KMnO4 without any additives or templates. The morphology of the composites is characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results demonstrate that the tetrahedral Mn3O4 nanoparticles have uniform sizes and are finely dispersed in the PANI matrix. The crystallinity and chemical constituents of the composites are characterized by powder X-ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR) and UV-vis spectrophotometry. Moreover, cyclic voltammetry (CV) measurements are used to characterize the electrochemical properties of PANI/Mn3O4 nanocomposites. The developed materials give a pair of redox peaks and have better operation stability, which indicates that the composites show distinct electrochemical performance. So the PANI/Mn3O4 nanocomposites would have potential applications in bioanalysis, biodetection and so on.
