To improve the CNT's dispersion, we tried to chemically modify the surface of MWNT with the butyllithium and the hexyllithium solution in sonicated reactor. The functionalized-MWNTs were characterized by Fourier transform infrared spectrometer(FT-IR) and Raman spectrophotometer. Also, we investigated the amount of alkyl moiety incorporated into MWNT's surface with Thermal gravimetric analyzer(TGA) and dispersibility in various organic solvents. Finally, we could find organic content was about 5% of the functionalized MWNT and dispersibility was enhanced in some solvents having intermediate solubility parameter.
