“…[33,[75][76][77][78] However, this stabilisation technique really took off in 2000 with the observation of fluorescence in surfactant stabilised nanotube dispersions [34] and the demonstration that similar dispersions could be used to prepare strong fibers [79] . Since then, thousands of papers have been published describing work which relies on surfactant stabilised nanotubes.…”

Many applications of carbon nanotubes require the exfoliation of the nanotubes to give individual tubes in the liquid phase. This requires the dispersion, exfoliation and stabilisation of nanotubes in a variety of liquids. In this paper we review recent work in this area, focusing on results from the author's group. We begin by reviewing stabilisation mechanisms before exploring research into the exfoliation of nanotubes in solvents, by using surfactants or biomolecules and by covalent attachment of molecules.The concentration dependence of the degree of exfoliation in each case will be highlighted. In addition we will discuss research into the dispersion mechanism for each dispersant type. Most importantly we have compared dispersion quality metrics for all dispersants. From this analysis, we conclude that functionalised nanotubes can be exfoliated to the greatest degree. Finally, we review the extension of this work to the liquid phase exfoliation of graphite to give graphene.

“…Several recent experiments on the preparation and mechanical characterization of CNT-polymer composites have also appeared. [2] [3] [4] These measurements suggest modest enhancements in strength characteristics of CNTembedded matrixes as compared to bare polymer matrixes. [4] Preliminary experiments and simulation studies on the thermal properties of carbon nanotubes show very high thermal conductivity.…”

Classical molecular dynamics (MD) simulations employing Brenner potential for intrananotube interactions and Van der Waals forces for polymer-nanotube interfaces are used to invetigate the thermal expansion and diffusion characteristics of carbon nanotube-polyethylene composites. Additions of carbon nanotubes to polymer matrix are found to increase the glass transition temperature T , and thermal expansion and diffusion coefficients in the composite above T . These findings could have implications in CNT composite processing, coating and painting applications.

We report on the first use of carbon-nanotube based films to produce crystals of proteins. The crystals nucleate on the surface of the film. The difficulty of crystallising proteins is a major bottleneck in the determination of the structure and function of biological molecules. The crystallisation of two model proteins and two medically relevant proteins was studied. Quantitative data on the crystallisation times of the model protein lysozyme are also presented. Two types of the nanotube film, one made with the surfactant Triton X-100 (TX-100) and one with gelatin, were tested. Both induce nucleation of the crystal phase at supersaturations at which the protein solution would otherwise remain clear, however the gelatin-based film induced nucleation down to much lower supersaturations for the two model proteins with which it was used. It appears that the interactions of gelatin with the protein molecules are particularly favourable to nucleation. Crystals of the C1 domain of the human cardiac myosin-binding protein-C that diffracted to a resolution of 1.6Å, were obtained on the TX-100 film. This is far superior to the best crystals obtained using standard techniques, which only diffracted to 3.0 Å. Thus, both our nanotube-based films are very promising candidates for future work on crystallising difficult-tocrystallise target proteins.3
