Comparative study on doping of polyaniline with graphene and multi-walled carbon nanotubes

摘要: This study reported the doping of polyaniline (PANI) with graphene (G) and multi-walled carbon nanotubes (MWCNTs) by in situ polymerization. The molecular structure PANI its composites was observed FTIR, which shows that intensity peaks are higher than pure due to charge transfer between graphitic allotropes. structural information crystallinity can be deduced from X-ray diffraction. morphological characterization transmission electron microscope, elucidated aniline molecules were physically adsorbed polymerized on surface MWCNTs π–π* interaction. represents as an external layer several diameters depending deposition degree, where cores G MWCNTs. conductivity measurement clarified value 0.1 wt% matrix is 17 times without it.
