We report here a method that can be used to easily prepare bulk quantities of solubilizedcarbon nanotubes. The method is derived from Haddon's method in which we have modifiedthe separation process by using two Soxhlet extractors in the procedure. Both primary andsecondary amines could be used as starting materials to solubilize carbon nanotubes in ourprocess, and the solubilized multiwalled carbon nanotubes (MWNTs) were fully characterized.Owing to the large quantity of solubilized MWNTs obtained, several basic properties suchas the solubility and the percentage content of tubes in the solubilized samples have beendetermined and analyzed. Typical solubilized MWNT/polymer composites were also fabricatedand their electronic and thermal properties were investigated.
