Carbon nanotubes(CNTs) are difficult to disperse in solvents and polymer matrices. Therefore, CNTs have need to do modification from functional groups.In this study, to improve the CNT's dispersion, we tried to modify the CNT's surface by butyllithium and hexyllithium solution with multi-walled carbon nanotubes (MWNTs). To find the addition of small functional groups, we analyzed Raman spectrometer and thermogravimetric analysis (TGA) and used various solvents and investigated the dispersity. As a result, functional groups of attached the CNT's surface are confirmed through Raman and TGA. A small amount of functionalized-MWNTs is dispersed only in chloroform andtetrahydrofuran. |
