Enviromentaly friendly functionalization of carboxylated shortend multi-wall nanotubes with sunset yellow dye

Abstract

In this paper, the chemical functionalization of carboxylated shortend multi-walled carbon nanotubes (MWNT-COOH) by sunset yellow dye via esterification method in water have been investigated. The functionalized MWNTs were characterized by Fourier Transform Infrared spectroscopy (FT-IR), Raman spectroscopy, elemental analysis, scanning electron microscopy (SEM), Defunctionalization test and UV analysis.
