Macrocyclic pore-apertured carbon nanotube apparatus

摘要

A macrocyclic pore-apertured carbon nanotube apparatus is disclosed. The carbon nanotube apparatus can be used to filter or exclude ions, solutes in solution, as well as particles suspended in a colloidal mixture. The nanotube apparatus includes a carbon nanotube having a carboxylated portion at least one pore entrance and at least one molecular aperture adapted to be bonded to the carboxylated portion of the carbon nanotube. The molecular aperture is further adapted to prevent dissolved ions in a solution from entering the pore entrance. Methods for preparing and using the apparatus are also disclosed. The apparatus can also be incorporated into to filtration media for conducting reverse osmosis filtration.
