Commercially available Multiwalled Carbon Nanotubes (MWCNTs) were refluxed with nitric
acid in order to improve the density of the acidic surface functional groups. The formation of …

Functionalization is the process of introducing chemical functional groups on the surface of
the material. In this study, a multi-walled carbon nanotube (MWCNTs) was functionalized by …

Carbon nanotubes (CNT) have gained great interest for research in many applications
because of their unique characteristics, such as having high porosity, high surface area and …

Multi-walled carbon nanotubes (MWCNTs) were functionalized by different oxidative
treatments to insert polar groups on their surface. The treatments included sulfuric/nitric acid …

In the current research, the role of both concentrated nitric acid and ultrasound waves on
oxidation of multi-walled carbon nanotubes (MWNTs) was studied. The functionalized …

Cyclohexanol and xylene were used as carbon precursors, for synthesis of multiwall carbon
nanotubes (MWCNTs) arrays in a CVD system at temperature of 750° C, using nitrogen as …

A new purification procedure was used for the purification of multiwalled carbon nanotube
(MWCNTs) based on nitric acid oxidation. Using thermogravimetric analysis (TGA), and …

Multi-walled carbon nanotubes (MWCNTs) were chemically treated using nitric acid solution
for different time. Quantitative analysis of the crystallinity of the MWCNTs was performed by …

The effect of acid treatment on multiwalled carbon nanotubes (MWCNTs) was investigated
through analysis of their morphologies followed by atomic force microscopy (AFM). The …

Multi-walled carbon nanotubes (MWCNTs) with improved dispersion property have been
prepared by a mild and fast hydrothermal treatment. The hydrothermal process avoids using …
