A facile, efficient, and rapid covalent functionalization of multi-walled carbon nanotubes with natural amino acids under microwave irradiation

- Amino acid-functionalization of MWCNTs was carried out under microwave irradiation.
- This procedure is fast and simple, resulted in a high degree of functionalization.
- The surface modified MWCNTs could be easily dispersed in organic solvents.
- Amino acid-modified MWCNTs could provide an environmentally friendly alternative.
