The influence of the temperature in the organic modification of single walled carbon nanotubes

In this paper, a simple method to modify single walled carbon nanotubes (SWNTs) with ODA is introduced and the effect of reaction temperature is mainly researched. The FTIR spectrum and XRD were used to investigate the organic functional groups and crystal structure of carbon nanotube before and after modification. The mole percentages of ODA decorated on SWNTs to carbon atoms in SWNTs are calculated by weighing method. The results show that the temperature plays an important role in the modification process. The amount of organic functional group on the surface of SWNTs is increase with the temperature and the mole percentage of ODA/carbon atom is in range of 2.12 to 8.64%.
