文摘

Soluble, ultra-short (length < 60 nm), carboxylated, single-walled carbon nanotubes (SWNTs)have been prepared by a scalable process. This process, predicated on oleum's (100% H₂SO₄ with excessSO₃) ability to intercalate between individual SWNTs inside SWNT ropes, is a procedure that simultaneouslycuts and functionalizes SWNTs using a mixture of sulfuric and nitric acids. The solubility of these ultra-short SWNTs (US-SWNTs) in organic solvents, superacid and water is about 2 wt %. The availability ofsoluble US-SWNTs could open opportunities for forming high performance composites, blends, andcopolymers without inhibiting their processibility.
