✦ Synopsis

Functionalization with amine groups of MWNTs was achieved after such steps as carboxylation, acylation and amidation. XRD, Raman, FTIR, XPS, scanning electron microscopy (SEM) were used to investigate and determine the chemical structure and texture of the amino-functionalized MWNTs. By comparing with each other, it was found that the amino-functionalized MWNTs can improve their dispersion in H 2 O. However, concerning the results of XPS, SEM and dispersity analyses, other reactions may also have occurred, which influenced their dispersity in organic solvents.
