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.

AbstractIn this paper, the effects of multiwalled carbon nanotubes (MWCNTs) on the mechanical and damping properties of ultra-high performance concrete (UHPC) were investigated. The results show that the proper amount of MWCNTs can improve mechanical properties as well as the damping properties. For the mechanical properties, the compressive strength and flexural strength of the specimens increased with the increase of MWCNTs content in the range of 0~0.05% (mass ratio to cement). However, when the content of MWCNTs was more than 0.05wt.%, the mechanical properties of UHPC could not be improved continually because too many MWCNTs were difficult to disperse and agglomerated easily in UHPC. Similar laws also have been found for the damping property of UHPC. The loss factor of UHPC increased with the increase of MWCNTs content in the range of 0 ~ 0.05%. The incorporation of MWCNTs would introduce a large number of interfaces into UHPC, the friction and slip between interfaces were the main reasons for the improvement of the damping property of UHPC. However, when the content of MWCNTs was more than 0.05%, it was difficult to disperse effectively. As a result, the overall energy consumption efficiency of MWCNTs was decreased.

ABSTRACTThe incorporation of chemically modified multi-walled carbon nanotubes (MWNTs) have demonstrated, as an additive material to enhance the electrical conductivity, into the electrode gives rise to a highly improved rate capability of a super-capacitor. The preferential attack of potassium hydroxide on less disordered carbon results in the formation of high-performance MWNTs with increased surface area, electrical conductivity and sustained long tube morphology, simultaneously. It is envisaged that newly developed functional MWNTs will be utilized in various electrochemical systems, where high current is critically required.
