TLDR
In this article, single-walled carbon nanotubes (SWCNTs) were functionalized with amino groups via chemical modification of carboxyl groups introduced on the carbon nanotide surface.Abstract:
Single-walled carbon nanotubes (SWCNT) functionalized with amino groups were prepared via chemical modification of carboxyl groups introduced on the carbon nanotube surface. Two different approaches (amide and amine-moieties) were used to produce the amino-functionalized nanotubes. The amino-termination allows further chemistry of the functionalized SWCNTs and makes possible covalent bonding to polymers and biological systems such as DNA and carbohydrates. The functionalization of the SWCNTs was characterized in detail using FTIR and XPS.read more
