摘　　要：　纳米碳管(Carbonnanotubes,CNT)具有π π共轭电子结构,可与结构相似的聚合物(Polymer)通过范德华力结合形成复合材料。导电聚合物(Electricallyconductingpolymer,ECP)包覆多壁纳米碳管(Multi walledcarbonnanotubes,MWNT)后,可用于诸如超级电容器等电子器件。共轭发光聚合物修饰纳米碳管形成的CNT polymer复合材料,具有很强的发光性能,有望用于电子接收器和光电器件。通过连结氨基聚合物,可使多壁纳米碳管溶解和功能化,从而将纳米碳管引入生物学系统中。研究结果表明,CNT polymer复合物有许多潜在的应用,有待进一步发展。Carbon nanotubes (CNTs) which have pi-pi conjugated electronic structure, can be functionalized by forming composites with some polymers with similar structure through van der Waals forces. CNTs coated with electronic conducting polymers (ECP) can be used in electronic devices such as supercapacitors. CNTs modified by conjugated luminescent polymers can form CNT/polymer composites, which have strong luminescence, and these photo-excited composites may be promising as electron acceptors and optoexcited devices. CNTs can also be functionalized and solubilized by attaching aminopolymers, as a result, they may find applications in biological systems. The state-of-the-art research results demonstrate that CNT/polymer composites have many promising applications to be developed and exploited.
