Polyaniline/multiwalled carbon nanotube composite films have been fabricated. It is shown that the nanotubes affect the free N–H environment and quinoid units along the polymer backbone. A 10-fold increase in conductivity is observed and elemental analysis indicates that the nanotubes compete with chloride ion during HCl doping (see Figure).
Zengin et al. (2002) studied this question.
