Abstract

The effects of the surface modification of carbon nanotubes (CNTs) on the dispersion stability and electrical conductivity of CNT/polyaniline (PAni) composites were investigated. The surface of the CNTs was modified with acid mixtures, potassium persulfate (KPS) and sodium dodecylsulfate. UV-visible spectral data indicate that the CNTs treated first with the acid mixture and then with KPS show the best dispersion stability. The acid mixture-treated CNT/PAni composite showed the highest conductivity of 16.5 S cm^-1.
