Abstract: The authors have developed a method for the functionalization of single-walled carbon nanotubes (SWCNTs). The functionalization of the SWCNTs is useful in helping to produce a better dispersion of nanotubes throughout a polymer matrix. Better dispersion of nanotubes was thought to result in an improvement in the mechanical, electrical, and thermal properties of nanocomposite polymers. It was determined that the method produced effective surface modification of the nanotubes. The elastic modulus and thermal conductivities of the nanocomposites seemed to be unaffected by the functionalization of the SWCNTs; however, the flexural strength of the nanocomposites was reduced.
