    • 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.
    • 本发明包括用于碳纳米管的化学改性的新方法。 这种方法涉及多壁碳纳米管和单壁碳纳米管的衍生,包括小直径(约0.7nm)的单壁碳纳米管与重氮物质。 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末端。 这些化学改性的纳米管可用于聚合物复合材料,分子电子应用和传感器装置。 衍生化的方法包括电化学诱导反应,热诱导反应(通过原位产生重氮化合物或预形成的重氮化合物)和光化学诱导反应。 衍生化导致纳米管的光谱性质的显着变化。 估计功能的程度约为 在具有功能部分的纳米管中每20至30个碳中有1个。 这种电化学还原方法可适用于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,衍生的纳米管与聚合物基质化学相容,允许将纳米管的性质(例如机械强度或电导率)转移到复合材料的整体性能上。 此外,当用合适的化学基团改性时,基团可以聚合形成包括碳纳米管的聚合物。
