Abstract
A forward osmosis membrane having a high chemical resistance includes a backing layer, a selective layer, and a hydrophilic support layer sandwiched between the backing layer and the selective layer. The hydrophilic support layer includes a plurality of nanostructures, each of which includes a carbon nanotube and a hydrophilic film coated around the carbon nanotube, and has an outer layer defined by the hydrophilic films of the nanostructures to prevent the selective layer from penetrating into the hydrophilic support layer.
