Functionalized single-walled nanotubes and methods thereof

摘要

Described are single-walled metal oxide nanotubes having a plurality of organic functional units or moieties bonded generally in a covalent manner to the inner wall of the single-walled nanotubes. Functionalization of the single-walled metal oxide nanotubes is performed in a single-step during synthesis of the nanotubes. The organic functional units are found dispersed throughout the length of the inner wall and not sterically hindered or contained at only the mouth or ends of the single-walled metal oxide nanotubes.

主权项

1. A functionalized single-walled metal-oxide nanotube comprising:
a metal-oxide nanotube having a single wall and opposing ends; and a quantity of organic functional units incorporated on the inner surface of the single wall; wherein the organic functional units are covalently bound to the inner surface of the single wall; wherein the organic functional units are substituted for hydroxyl units on the inner surface of the single wall; wherein the organic functional units bind to a component of the single wall, the component consisting of a Group IVA element; and wherein the organic functional units are incorporated at various locations along a length of the inner surface of the single wall and wherein the organic functional units are not localized at one or more of the opposing ends of the single wall.
