Advances in the interfacial bonding characteristics of carbon nanotube/polymer composites

The excellent mechanical properties of carbon nanotube (CNT)make it a preferred reinforcement for composites.The mechanical properties of CNT/polymer composites are greatly determined by the interfacial bonding characteristics.Both research methods and research progresses of the interfacial bonding characteristics of CNT/pol-ymer composites were reviewed in this paper.Microscopic characterization techniques,raman spectroscopy analysis technology and nano-mechanical pull-out method were used in the experiment.Molecular simulation method simula-ted the pull-out process of CNT from the polymer matrix by applying displacement and force to CNT.The effects of polymer matrix (including type,crystal structure and density)and CNT (including chirality,diameter and function-al processing)on the interfacial bonding characteristics of CNT/polymer composites were summarized and the signi-ficant future research directions of this field were prospected.
