CNTs were first pre-treated using acid solution (HNO3) to obtain CNTs functionalized with carboxylic groups. Subsequently, the stearyl alcohol was grafted onto CNT with the assistance of dehydrating agent, N,N'-dicyclohexyl-carbodiimide. Excellent dispersion in organic solvents such as acetone, THF, and chloroform was found for the modified CNTs (CNT-C18). In addition, the PBS/CNTs nanocomposites were then prepared through simple melt-blending. Mechanical properties, thermal behavior, conductivity of resultant polymer/CNT composites were investigated. The results show that excellent dispersion of nanotubes in the PBS matrices was achieved.
