Methods for the chemical modification of carbon nanotubes 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, and photochemically induced reactions. 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.
碳纳米管的化学修饰方法包括使用重氮化物对多壁和单壁碳纳米管进行衍生化,包括直径小于0.7纳米的单壁碳纳米管。该方法允许将各种有机化合物化学附着到碳纳米管的侧面和端部。这些化学修饰的纳米管在聚合物复合材料、分子电子应用和传感器设备中有应用。衍生化的方法包括电化学诱导反应、热诱导反应和光化学诱导反应。此外,当用适当的化学基团修饰时,衍生化的纳米管与聚合物基质化学相容,使得纳米管的性质(如力学强度或电导率)能够转移到复合材料整体的性质上。此外,当用适当的化学基团修饰时,这些基团可以聚合形成包含碳纳米管的聚合物。
