Good Electrical Performance Functionalized Carbon Nanotubes 

For the functionalized carbon nanotubes, we could do functionalized SWCNT, functionalized MWCNT. For what functionalized group you need, kindly contact us for further information.

Introduction for functionalized carbon nanotubes:

1. A functionalized nanotube might have mechanical, optical or electrical properties。

2. Covalent functionalization is based on the formation of a covalent linkage between functional entities and the carbon skeleton of nanotubes. It could also be divided into direct covalent sidewall functionalization and indirect covalent functionalization with carboxylic groups on the surface of CNTs.

3. Indirect covalent functionalization takes advantage of chemical transformations of carboxylic groups at the open ends and holes in the sidewalls. These carboxylic groups might have existed on the as-grown CNTs and also be further generated during oxidative purification。

4. In order to increase the reactivity of CNTs, the carboxylic acid groups usually need to be converted into acid chloride and then undergo an esterification or amidation reaction.

5. Functionalization inside the tubes in the form of covalent chemical bonds has not yet been demonstrated but chemical reactions which lead to products not observed outside the tubes occur.
