Dispersion of Multiwalled Carbon Nanotubes with Water-Soluble Polyaniline Blend Poly(Sodium 4-Styrenesulfonate)

Abstract

Water-soluble polyaniline blend poly(sodium 4-styrenesulfonate), (PANI.PSS) was used to disperse multiwalled carbon nanotubes (MWCNTs) by noncovalent surface modification. The anionic of PANI.PSS solution was prepared by interfacial polymerization of aniline monomer in the presence of PSS as the blending reagent to provide water solubility. The optimal conditions to prepare stable modified MWCNTs/PANI.PSS aqueous dispersions are presented. The interaction of MWCNTs and PANI.PSS have been investigated and explained according to the result of UV-Vis spectroscopy and zeta potential analysis. The MWCNTs/PANI.PSS complex solution was further confirmed more evidence by Transmission electron microscopy (TEM). Results showed that the MWCNTs dispersed with PANI.PSS are highly dispersible in water, which open up the new possibilities for the fabrication of composite films.
