Abstract
A method for fabricating a reverse osmosis membrane is described. The method includes aligning a plurality of carbon nanotubes at the interface of two liquids, the first liquid being an aqueous layer, and the second layer being an organic layer that is immiscible to the aqueous layer, forming a thin layer selective membrane around the aligned carbon nanotubes at the interface of the two liquids, and bonding the thin layer selective membrane/carbon nanotube composite onto a structural support layer.
