چکیده

Single-walled carbon nanotubes were chemically functionalized by virtue of the interactions between the nanotube-bound carboxylic moieties and octadecylamine ligands. The electronic conductivity properties of the resulting nanotubes were probed voltammetrically. Two approaches were employed. The first entailed the fabrication of a nanotube monolayer at the air|water interface and the conductivity was measured in situ with a vertically aligned interdigitated arrays (IDAs) electrode. The overall current profiles are analogous to those of a C T w b ©

Synthesis and characterization of functionalized single - walled carbon nanotube/ chitosan/polyaniline nanocomposite

In this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. For this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. In other step, aniline monomers and chitosan were polymerized in the presence of Iron (III) chloride to sy...

Linkage of doxycycline onto functionalized multi-walled carbon nanotube and morphological characterization

In this paper functionalized multiwall carbon nanotubes (FMWCNT) were modified using doxycycline, containing reactable nitrogen, which can attach chemically to functionalized MWCNT. The synthesized nano compounds were characterized by Fourier transform infrared spectroscopy (FT-IR) and Raman spectroscopy. These spectrums proved the existence of nitrogen atoms of amide functional groups. The mor...
