Sulphonated polyaniline/MWCNTs nanocomposite: preparation and promising thermoelectric performance

Here is concise description of in situ prepared polyaniline and its nanocomposite with multi-walled carbon nanotubes followed by sulfonation. Thus, prepared materials were characterized by Fourier transform infrared spectroscopy, X-ray diffraction analysis, feld emission scanning electron microscopy and electro-thermal analysis. Incorporation of ultrasonicated multi-walled carbon nanotubes signifcantly increased the electrical conductivity due to π–π interaction of polyaniline with multi-walled carbon nanotubes and its back to back sulfonation further rendered fortifcation. Finally, as-prepared nanocomposite showed greater electrical conductivity as well as improved thermal stability in terms of DC electrical conductivity retention under isothermal and cyclic aging conditions.
