Résumé     
We present an easy and reliable method of functionalizing and dispersing single-walled carbon nanotubes (SWCNTs) for nanocomposite production. This was achieved via a mixture of the concentrated acids HNO3/H2SO4, followed by sonication in appropriate solvents (Ethanol, Acetone and/or Dimethylformamide). SWCNTs were functionalized to attach carboxylic moieties on the walls of the nanotubes, which aided in the production of SWCNTs suspensions in acetone, ethanol and dimethylformamide in which nanotubes remained dispersed for a period of two (2) weeks. Energy dispersion analysis (EDS), scanning electron microscopy (SEM) and Raman spectroscopy were used to characterize the functionalized SWCNTs.
