Improved processing of polyaniline-carbon nanotube nanocomposites via water dispersions

Abstract

In this work we show a nanostructured composite between polyaniline (PANI) and multi-wall carbon nanotubes (MWNTs) that can be dispersed in aqueous solutions in high concentrations, which allows different kinds of processing. The content of MWNTs in these composites can be as high as 50% wt. without losing its water dispersibility. The low size of the nanostructures, the hydrophyllicity of PANI in the emeraldine salt state, and the good PANI-MWNT interaction are responsible for the high stability and homogeneity of the water dispersions of the material.
