摘要： The present invention is directed toward a method of sidewall-functionalizing single-walled carbon nanotubes (SWNTs) through C—N bond forming substitution reactions with fluorinated SWNTs (fluoronanotubes), and to the sidewall-functionalized SWNTs comprising C—N bonds between carbons of the SWNT sidewall and nitrogens of the functionalizing groups made by these methods. Furthermore, when diamine species are utilized as reactants, novel materials like crosslinked SWNTs and “nanotube-nylons” can be generated. In some embodiments, SWNTs with functional groups covalently attached to their side walls through C—N bonds are prepared by either the direct interaction of fluoronanotubes with terminal alkylidene diamines or diethanolamine, or by a two-step procedure involving consecutive treatments with Li3N in diglyme and RCl (R═H, n-butyl, benzyl) reagents. Evidence for sidewall attachment of amine-derived groups has been provided by Raman, FTIR, and UV-vis-NIR spectra, SEM/EDAX and TEM data, and thermal degradation studies. The demonstrated new C—N functionalization methods offer a wide range of further SWNT derivatizations, including their covalent binding to aminoacids, DNA, and polymer matrixes.

摘要： The present invention is directed to methods of forming sidewall-functionalized carbon nanotubes, wherein such functionalized carbon nanotubes have hydroxyl-terminated moieties covalently attached to their sidewalls. Generally, such methods involve chemistry on carbon nanotubes that have first been fluorinated. In some embodiments, fluorinated carbon nanotubes (“fluoronanotubes”) are reacted with mono-metal salts of a dialcohol, MO—R—OH, where M is a metal and R is hydrocarbon or other organic chain and/or ring structural unit. In such embodiments, —O—R—OH displaces —F on the nanotube, the fluorine leaving as MF. Generally, such mono-metal salts are formed in situ by the addition of MOH to one or more dialcohols in which the fluoronanotubes have been dispersed. In some embodiments, fluoronanotubes are reacted with amino alcohols, such as being of the type H2N—R—OH, wherein —N(H)—R—OH displaces —F on the nanotube, the fluorine leaving as HF.

摘要： A method for functionalizing the wall of single-wall or multi-wall carbon nanotubes involves the use of acyl peroxides to generate carbon-centered free radicals. The method allows for the chemical attachment of a variety of functional groups to the wall or end cap of carbon nanotubes through covalent carbon bonds without destroying the wall or endcap structure of the nanotube. Carbon-centered radicals generated from acyl peroxides can have terminal functional groups that provide sites for further reaction with other compounds. Organic groups with terminal carboxylic acid functionality can be converted to an acyl chloride and further reacted with an amine to form an amide or with a diamine to form an amide with terminal amine. The reactive functional groups attached to the nanotubes provide improved solvent dispersibility and provide reaction sites for monomers for incorporation in polymer structures. The nanotubes can also be functionalized by generating free radicals from organic sulfoxides.
