Insight Into

ABSTRACTWe report the use of high power ultrasonic agitation to create inelastic deformations in multiwalled carbon nanotubes. Using STM coupled with TEM we show that this damage can range from kinking to breaking of continuous tube walls into segments. Such deformed tubes provide an insight into the role of re-hybridization in the electrical and mechanical properties of tubes.

Functionalized multiwalled carbon nanotubes (MWCNTs) by various groups (carboxyl or amino) can improve the properties of anti-tumoral drugs (cisplatin, docetaxel, zometa). Functionalization was evidenced by infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). Platinum ions released in simulated body fluid (SBF) were measured by inductively coupled plasma ion spectrometry (ICP-MS).

Multi-walled carbon nanotubes (MWCNTs) are grafted with hyperbranched polysiloxane ( HBPSi ) by an efficient hydrosilylation method. In this hydrosilylation process, hydroxylated MWCNTs (HO-MWCNTs) are first functionalized by triethoxyvinylsilane to introduce carbon–carbon double bonds ( C = C ) on the surface of MWCNTs. The C = C is then reacted with the monomer of methylbis(dimethylvinylsiloxy)silane in the presence of the platinum–carbon catalyst, thus HBPSi is ultimately grafted on the surface of MWCNTs. Fourier transform infrared spectrometry (FTIR), Transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS) are employed to characterize the changes in MWCNTs surface morphology, chemistry and physical conditions at different processing stages. The content of HBPSi on the surface of MWCNTs was also measured by the thermogravimetric analysis (TGA). The results indicate that the HBPSi successfully grafted on the surface of MWCNTs, and the dispersion of MWCNTs in organic solvent is also improved after functionalization.

In an attempt to explore the possibility of using carbon nanotubes (CNTs) as efficient adsorbents for removal of pollutants from the contaminated water, the adsorption ofp-nitrophenol (PNP) on raw multiwalled carbon nanotubes (r.MWNTs) with different outer diameters, various functionalized multiwalled carbon nanotubes (f-MWNTs), raw single-walled carbon nanotubes (r.SWNTs) and oxidized single-walled carbon nanotubes (ox-SWNTs) has been investigated. The ox-SWNTs showed better adsorption ability for PNP with different concentrations, while lower uptake capacity was found for all of the r.MWNTs andf-MWNTs. The removal efficiency of PNP by ox-SWNTs was around 98%, indicating that ox-SWNTs possess a great potential application prospect for removing PNP from aqueous solutions.

Carbon nanotubes, carbon spheres and slices of vertically aligned multiwalled carbon nanotubes (MWNTs) were synthesized simultaneously by chemical vapour deposition (CVD). Electron microscopy image showed carbon nanotubes were multiwalled carbon nanotubes, several micrometers in length. Carbon spheres were of uniform diameter (about 1 μm). Slices of vertically aligned multiwalled carbon nanotubes were about 5 mm in length, 3 mm in width and 8 μm in thickness. The interior of the slice was composed of densely packed, vertical aligned MWNTs, and faceted carbon beads. They were stable and easily separated from each other. The formation mechanism of slice was also discussed.
