Carbon nanotube (CNT)/polymer nanocomposites are recently one of the research interest in the field of nanomaterials.The recent progress on reinforced and functional CNT/polymer nanocomposites has been reviewed briefly in this paper.The effects of CNT’s dispersion
orientation and interaction at the CNT/matrix interface on the mechanical properties of these nanocomposites have been discussed in detail.Some new optoelectronic properties of various CNT/polymer nanocomposites have been described.The research direction of CNT/polymer nanocomposites is also presented.
