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.

Functionalized single-walled nanotubes and methods thereof

The present invention discloses a nanocomposite material having single-walled aluminosilicate nanotube in polymer, a membrane comprising such nanocomposite material, and the method of making the nanocomposite material, in which the composite material has high volume fraction of well-dispersed nanotubes. A gel-phased single-walled aluminosilicate nanotube is first prepared and then mixed with a polymer matrix to yield the composite material.

Single-walled metal oxide and metal sulphide nanotubes/polymer composites

Provided herein are methods for dehydrating single-walled metal oxide nanotubes by heating the SWNT under vacuum at 250-300&#xb0; C.; methods of dehydroxylating SWNT, comprising heating the SWNT under vacuum at 300-340&#xb0; C., and methods for maximizing the pore volume of a SWNT, comprising heating the SWNT at 300&#xb0; C. under vacuum to partially dehydroxylate and dehydrate the SWNT; methods of modifying the inner surface of a single walled aluminosilicate nanotube (SWNT), comprising dehydration or dehydration and dehydroxylation, followed by reacting the SWNT with a derivative under anhydrous conditions to produce a SWNT that is derivatized on its inner surface. The invention also includes single-walled nanotubes produced by the methods of the invention.
