Abstract

A method of forming a two-layered membrane by immersion precipitation including: depositing a first hydrophilic polymer solution with a formulation optimized to produce a high performance porous layer; depositing on top of the first hydrophilic polymer solution a second, different hydrophilic polymer solution optimized to produce a high performance dense layer; and forming the two-layer polymer solution into one of a forward osmosis membrane and a pressure retarded osmosis membrane by bringing the second, different hydrophilic polymer solution into contact with water to form the dense layer. A two-layered membrane formed by immersion precipitation includes: a porous layer formed from a first hydrophilic polymer solution with a formulation optimized to produce a high performance porous layer; and a dense layer on top of and supported by the porous layer, the dense layer formed from a second, different hydrophilic polymer solution optimized to produce a high performance dense layer.
