Abstract
Processes for manufacturing a thin film composite membrane comprising multi-walled carbon nanotubes include contacting under interfacial polymerization conditions an organic solution comprising a polyacid halide with an aqueous solution comprising a polyamine to form a thin film composite membrane on a surface of a porous base membrane; at least one of the organic solution and the aqueous solution further including multi-walled carbon nanotubes having an outside diameter of less than about 30 nm.
