Abstract: Carbon nanotube (CNT) exhibits excellent flexibility, ultra-high strength,good chemical stability properties as well as nanometer scale diameter and high aspect ratio, which make it an ideal reinforcement filler for high strength thermoplastic polymer composites. However, since CNT usually forms stable bundles due to strong van der Waals interactions, CNT is extremely difficult to be dispersed and aligned in polymer matrix. This paper reviews recent research progress of the related technology to improve the surface modification and dispersion of CNT in thermoplastic polymer matrix, and also introduces the physical properties and applications of the nanocomposites.Finally the current key problem of CNT application in thermoplastic polymer composites is elaborated.
