In situ oxidative polymerization of aniline in the presence of manganese dioxide and preparation of polyaniline/MnO 2 nanocomposite

摘要

The method used in this paper is in situ process for the synthesis of polyaniline (PANI)/manganese dioxide. Polymerization of aniline was carried out in a one-pot reaction vessel, and MnO~(2)particles were influenced by the PANI pores to yield a PANI/MnO~(2)nanocomposite. Morphology analysis showed soft and flat surfaces of the PANI/MnO~(2)nanocomposite by scanning electron microscopy, and Fourier transform infrared spectroscopy revealed polyaniline being intercalated between manganese oxide layers. Findings showed that the MnO~(2)particles should be doped on the network of polyaniline; therefore, the morphology of the product is in the same line with the results.
