摘要：

A nanocomposite of well dispersed carbon nanotube (CNT) in acrylonitrile-butadiene-styrene (ABS) matrix was prepared by solution processing. CNT dispersibility in four different solvents was studied experimentally and theoretically and the best solvent was selected to prepare the nanocomposite. The nanocomposite morphology was examined by transmission electron microscopy and optical microscopy to determine the nanotube level of dispersion and the location of CNT in the ABS matrix. Solubility parameter concept was used to explain the location of CNT in the ABS matrix. As a result of perfect dispersion and selective localization of CNT in the SAN phase of the ABS matrix, the electrical conductivity of the nanocomposite as function of filler content showed that the nanocomposite exhibit a typical percolation behavior with a percolation threshold of only 0.06 vol.%.
