- Abstract
Novel composites were prepared by oxidative polymerization of aniline over hybrid carbon nanostructured assemblage consisting of graphene and amine functionalized multiwalled carbon nanotubes. The chemical structure of the obtained composites has been confirmed by UV-visible Spectroscopy and Fourier transform infrared spectroscopy. To know about the crystalline properties of the composites, X-ray diffraction studies have been done. The structural and morphological properties of the composites were examined by scanning electron microscopy. The composite having thinnest polymer film exhibited highest conductivity of 0.11 S/cm and maximum electromagnetic interference shielding effectiveness value of 21 dB obtained in the frequency range 12-18 GHz (KU-band).
