    • The invention incorporates new processes for the chemical modification of carbon nanotubes. Such processes involve the derivatization of multi- and single-wall carbon nanotubes, including small diameter ( ca . 0.7 nm) single-wall carbon nanotubes, with diazonium species. The method allows the chemical attachment of a variety of organic compounds to the side and ends of carbon nanotubes. These chemically modified nanotubes have applications in polymer composite materials, molecular electronic applications and sensor devices. The methods of derivatization include electrochemical induced reactions thermally induced reactions (via in-situ generation of diazonium compounds or pre-formed diazonium compounds), and photochemically induced reactions. The derivatization causes significant changes in the spectroscopic properties of the nanotubes. The estimated degree of functionality is ca . 1 out of every 20 to 30 carbons in a nanotube bearing a functionality moiety. Such electrochemical reduction processes can be adapted to apply site-selective chemical functionalization of nanotubes. Moreover, when modified with suitable chemical groups, the derivatized nanotubes are chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as, mechanical strength or electrical conductivity) to the properties of the composite material as a whole. Furthermore, when modified with suitable chemical groups, the groups can be polymerized to form a polymer that includes carbon nanotubes.
    • 本发明结合了碳纳米管化学修饰的新方法。 这些过程涉及多壁和单壁碳纳米管的衍生,包括小直径(大约0.7纳米)单壁碳纳米管,以及重氮化合物。 该方法允许将各种有机化合物化学连接到碳纳米管的侧面和端部。 这些化学修饰的纳米管可用于聚合物复合材料,分子电子应用和传感器设备。 衍生化方法包括电化学诱导反应热诱导反应(通过原位生成重氮化合物或预先形成的重氮化合物)和光化学诱导反应。 衍生化引起纳米管的光谱性质的显着变化。 估计的功能程度是ca。 在带有功能性部分的纳米管中每20至30个碳中有1个。 这种电化学还原过程可以适用于应用纳米管的位点选择性化学官能化。 此外,当用合适的化学基团改性时,衍生化的纳米管与聚合物基体化学相容,从而允许纳米管的性质(例如机械强度或电导率)整体上转化为复合材料的性质。 此外,当用合适的化学基团改性时,这些基团可以聚合形成包含碳纳米管的聚合物。
