Preparation and Electrochemical Studies of Layered PANI/HNb3O8 Nanocomposite
Aniline monomers could be easily inserted into and polymerized within the interlayers of HNb3O delta. The conformation and electrochemical properties of the resulting nanocomoposites were discussed in detail. Two different mechanisms were proposed for the polymerization of monomers within the confined interlayers initiated by chemical oxidants and microwave irradiation, respectively. The analyses of thermogravimetric/differential calorimetric analyses, X-ray diffraction, and Fourier transform infrared spectra indicated that the aromatic rings of the interlayered polyaniline (PANI) Could be parallel with or perpendicular to the inorganic slabs, and the interlayered PANI molecules were emeraldine salt and protonated by the protons of layered inorganic acid host. The cyclic voltammetry revealed that the properties of the layered host and the interlayer height have an effect on the redox behavior of the corresponding nanocomposites. Compared with the nanocomposites in which the aromatic rings were parallel with the inorganic stabs, the nanocomposites in which the aromatic rings were perpendicular to the slabs demonstrated a higher conductivity and electrochemical activity.
