“…Very soon after their discovery the nanotubes were proposed as possible nano sized vessels for chemical reactions [23,24]. Although this progress has been partly hindered due to difficulties to probe the reactions inside the single walled carbon nanotubes (SWCNTs) some experimental studies in this direction have been reported lately [15,[25][26][27][28]. As suggested by McIntosh et al the nanotubes encapsulating the diamondoids may both guide the molecules into an ordered arrangement and in particular suppress the free rotation of the diamondoids [3].…”

“…In order to construct functional elements of diamondoid-based NEMS devices a controllable method to arrange and possibly connect the diamondoids with strong bonds is desirable. An intriguing possibility is to use carbon nanotubes (CNT) as vessels in the same way as for fullerenes [7][8][9][10][11][12][13][14], polymers [15] and other organic [13,[16][17][18] and inorganic materials [19][20][21][22].

We have encapsulated adamantane (C 10 H 16 ) in single-and multi walled carbon nanotubes.Adamantane is a high symmetry cage like molecule with point group symmetry, T d and can be considered as a hydrogen-terminated diamond fragment. We confirmed and identified the successful filling by high resolution transmission electron microscopy, 13 C nuclear magnetic resonance, and infrared and Raman spectroscopy. 13C nuclear magnetic resonance of the adamantane filled nanotubes reveals that the adamantane molecules stop rotating after encapsulation. A blue-shift of the Raman active radial breathing modes of the carbon nanotubes supports this and suggests a significant interaction between encapsulated adamantane molecules and the single wall nanotubes. The encapsulated adamantane molecules exhibit red shifted infrared C-H vibration modes which we assign to a slight elongation of the C-H bonds. We observe both a nanotube diameter dependence of the adamantane fill ratio and a release rate of adamantane from the CNTs that depends on the CNT diameters.

“…[1] Many composites based on CNTs have been developed because of their unusual physical properties and large application potential, covering a broad range in nanotechnology. [2][3][4][5][6][7] On the other hand, CNTs are insoluble in all solvents and difficult to handle because they are large molecules with thousands of carbon atoms in an aromatic delocalized system. [8] Therefore, the functionalization of CNTs is beneficial to tailor the structure and properties of CNTs, improve the solubility and compatibility of CNTs, and prepare novel CNT-based composites.…”

“…In addition, no toxic residual solvents remain in the final products making the process suitable for special applications of nanocomposites in bioengineering and biomedicine. [2] Because of these excellent properties, a range of polymer composites have been prepared using scCO 2 as the green solvent. [8][9][10][11][12][13][14][15][16][17] This study presents a 'green' method for preparing a biocompatible composite by in situ polymerization of 2-hydroxylethyl methacrylate in the presence of modified multi-wall nanotubes (MWNTs) in scCO 2 .…”

A nanocomposite consisting of multi-wall nanotubes (MWNTs) grafted with a biocompatible polymer poly(2-hydroxyethyl methacrylate) was prepared by in situ polymerization in supercritical carbon dioxide. The surface of the MWNTs was first surface modified with hydroxyl groups in the solution of KMnO 4 and a phase-transfer catalyst. MWNT-OH was then functionalized with vinyl groups using a silane coupling agent, γ-methacryloxypropyltrimethoxysilane. The silane groups can improve the dipersion of MWNTs in supercritical carbon dioxide, while the terminal vinyl groups help fabricate polymer chains on the MWNT surface. The as-synthesized products were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and thermo-gravimetric analysis. The SEM and TEM images showed that the nanotubes were well coated with the polymer shell. The composite had higher thermal stability than the pure polymer and dispersed well in methanol. This biocompatible polymer composite was prepared using a green method and is expected to be useful as a biomaterial composite with potential applications in the biological field.

“…and doping the CNTs with electrons donors or acceptors [13]. In many of the developed modification strategies of CNTs, besides ornamentation with conducting polymers and ceramics [14,15], decorations of CNTs by metal nanoparticles (NPs) have focused more attraction. Except the coupling/assembly NPs to CNTs through some functional groups [16 -18] and the filling metal NPs into CNTs during the synthesis process [19,20], direct deposition NPs on CNTs have been reported [21,22].…”

Using multiwalled carbon nanotubes (MWNTs) as templates, noble metal (Au, Ag, Pt or Pd) nanoparticles (NPs) were fabricated in situ by electrochemistry with a diameter of 40 -60 nm. Further, catalytic behaviors of these composite materials were investigated. Experiments showed that such carbon nanotubes decorated with Pd NPs modified glassy carbon electrodes exhibited higher electrocatalytic ability to some molecules such as evolution of hydrogen, reduction of oxygen and oxidation of ascorbic acid. Atomic force microscopy, X-ray photoelectron spectroscopy and cyclic voltammetry were used to characterize the film formation and their properties.
