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.

Silicon Carbide nano particle
Silicon Carbide nano particle dosage influencing on composite friction performance

Silicon Carbide nano particle dosage influencing on composite friction performance       For Silicon carbide nano particle is with Moh’s hardness about 9.2 which is a hard material. With its hardness, SiC nano powder is suitable to be additive for composite material and improve their toughened and strengthened.        For SiC nano additive has different influence to the relative density, hardness, electrical conductivity and friction and wear properties of the composites. Generally the relative density of the composites decreased with the increase of the content of nano SiC particles. The hardness of the composites increased with the increase of the content of SiC nano particles, but when the nano  SiC particles agglomerated, the hardness increased . However the content of silicon carbide nano powder affect to the conductivity of material is opposite. When the content of  SiC nano particle increase the conductivity of the composite decreases. According to some study when the content of SiC particles is about 0.5% -3%, the wear rate of the composites decreases with the increase of SiC content. When the SiC content is more than 3%, the wear rate of the composites increased with the increase of the content of  SiC nano-particles. The abrasive wear and the friction coefficient decreased with the increase of the SiC content.
