New types of functionalised, water-soluble carbon nanotubes
Microwave assisted CNT purification and functionalisation to improve dispersion have been investigated. The optimisation of the amidation reaction of carboxylated CNTs is being carried out with a view to explore the extent of covalent and non-covalent functionalisation. All of the corresponding CNT products have been characterised using DSC/DTA-TGA and FTIR spectroscopy. The efficiency of removal of metal catalyst under microwave conditions was compared with other conventional procedures.
