摘　　要：碳纳米管(CNTs)具有很多优良性能,但由于在聚合物基体分散性差,限制了其广泛应用。超支化聚合物是高度支化的大分子,具有低黏度、高溶解性及含有大量末端基团等特点。利用超支化聚合物共价修饰CNTs,不仅可以提高CNTs在聚合物基体中的分散性,还能使CNTs拥有新的功能。介绍了超支化聚合物共价修饰CNTs的方法,探讨了其在生物医学、纳米材料等方面的应用前景,最后对超支化聚合物共价修饰CNTs的发展提出了建议。Carbon nanotubes（CNTs） have many good properties.However,the poor solubility limits their application in many promising fields.Hyperbranched polymers which are highly branched macromolecules have low viscosity,high solubility,lots of end-groups,and so on.CNTs modified covalently by hyperbranched polymers,can not only enhance the compatibility and interface adhesion between polymer matrix and CNTs,but also endow CNTs with new properties.The preparation of covalent modification of CNTs with hyperbranched polymers is introduced.The future application on biomedical materials,nanometer materials,etc.,is proposed.Finally,some development suggestions for covalent modification of CNTs with hyperbranched polymers are put forward.
