Methodology for homogeneous dispersion of single-walled carbon nanotubes by physical modification

Science and technology on carbon nanotubes (CNTs) are an expanding field aiming at ascertaining their intrinsic properties and taking advantage of their inviting possibilities. Dealing with CNTs has faced the problem of insolubility in both organic and inorganic solvents due to the strong interaction therein. Here we review the recent progress as well as our approaches to the solubilization of CNTs based on a physical modification method. Especially, the review focuses on the 'individual' solubilization of pristine CNTs in solvents. Individual solubilization of CNTs is imperative in many research programs such as chemical modification of CNTs via organic reactions, characterization of CNTs chiral indices as well as separation of these mixtures, preparation of composites with polymers, fabrication of CNTs-based nanoelectronics devices and so forth.
