Scaffold‐like nanofiber support layers are fabricated with an interconnected pore structure, which is superior to conventional phase‐inversion support layers with tortuous sponge‐like structures. This successfully breaks the intrinsic bottleneck of internal concentration polarization in forward osmosis (FO) membranes and results in a high water production rate and energy savings.
