The aims of this study are the construction of carbon nanotube-based hybrid nanomaterials. The combination of carbon nanotubes and organic, inorganic and polymer materials may lead to the construction of navel nano carbonmaterials with high performances. The obtained results are summarized as follows.Carbon nanotubes are found to dissolve individually insolvents containing several kinds of amphiphiles carrying an aromatic moiety including anthryl, phenathryl and pyrenyl groups. The sollubilized nantube solutions were characterized by NMR, UV vis-near IR and Raman spectra.We have introduced an aromatic moiety to poly(styrene-alt-maleic anhydride). The synthesized copolymers were characterized by atomic force microscopy, UV-vis-near IR,NMR and Raman spectra and found that they act as "reactive carbon nanotube solubilizers" that should be useful for the design and construction of SWNTs/polymer composite nanomaterials with specific functions.We have already reported that double-stranded DNA dissolves SWNTs in aqueous solutions. DNA/carbon nanotube films were successfully formed by the alternating adsorption of poly(dC)-SWNTs and poly(dG)-SWNTs onto a quartz substrate. UV-vis-near IR spectra for the obtained DNA-SWNTs films showed absorption bands in the region of 500-600nm and 1000-1400 nm that are assignable to met-SWNTs and sem-SWNTs, respectively. The DNA-SWNTs films after the adsorption cycle of 50 times showed characteristic Raman peaks derived from the SWNTs on the substrate.

本研究的目的是构建碳纳米管基杂化纳米材料。碳纳米管与有机、无机及高分子材料的结合可以构筑出高性能的纳米碳材料。主要研究结果如下：碳纳米管在含有蒽基、菲基和芘基等芳香基团的两亲分子的溶剂中可以单独溶解。用NMR、UV-vis-near-IR和拉曼光谱对增溶的纳米管溶液进行了表征。通过原子力显微镜、紫外-可见-近红外光谱、核磁共振和拉曼光谱对合成的共聚物进行了表征，发现它们具有“活性碳纳米管增溶剂”的作用，这对于设计和构建具有特定功能的单壁碳纳米管/聚合物复合纳米材料具有重要意义。通过在石英基底上交替吸附poly（dC）-SWNTs和poly（dG）-SWNTs，成功地制备了DNA/碳纳米管薄膜。所得DNA-SWNTs薄膜的UV-vis-near IR光谱在500- 600 nm和1000-1400 nm区域分别显示出可归属于met-SWNTs和sem-SWNTs的吸收带。吸附循环50次后的DNA-SWNTs膜显示出来自基底上的SWNTs的特征拉曼峰。
