Abstract
A reverse osmosis composite membrane includes: a porous support; and a reverse osmosis membrane arranged on the porous support and containing a crosslinked polyamide and carbon nanotubes. The reverse osmosis membrane contains the carbon nanotubes that are disentangled in the crosslinked polyamide. A distribution of closest distances between the carbon nanotubes in the reverse osmosis membrane has a peak that is within a range of a thickness of the reverse osmosis membrane, and a half width of the peak is equal to or less than the thickness of the reverse osmosis membrane.
