Charge transport properties of water dispersible multiwall carbon nanotube-polyaniline composites

The transmission electron microscopy images of in situ prepared multiwall carbon nanotubes (MWNTs) and polyaniline (PANI) composites have shown that nanotubes are well dispersed in aqueous medium and the nanofibers of PANI has facilitated intertube transport. The onset frequency for the increase in conductivity is dependent on the MWNT weight percent and the negative magnetoresistance is attributed to the forward interference scattering mechanism in variable range hopping (VRH) transport.
