Selective Functionalization of Carbon Nanotubes: Part II

Different species are deposited at different distances.

An alternative method of low-temperature plasma functionalization of carbon nanotubes provides for the simultaneous attachment of molecular groups of multiple (typically two or three) different species or different mixtures of species to carbon nanotubes at different locations within the same apparatus. This method is based on similar principles, and involves the use of mostly the same basic apparatus, as those of the methods described in “Low-Temperature Plasma Functionalization of Carbon Nanotubes” (ARC-14661-1), NASA Tech Briefs, Vol. 28, No. 5 (May 2004), page 45.
