Disclosed is a membrane formed from a self-assembling diblock copolymer of chemical formula (I): wherein R^1 -R 4, n, and m are as described in the specification, which finds use in manufacturing a porous membrane. Embodiments of the membrane comprise the diblock copolymer which self-assembles into a cylindrical morphology. Also disclosed is a method of manufacturing such a membrane which comprises the step of hybrid casting a polymer solution containing the diblock copolymer to obtain a thin film, followed by evaporation of some of the solvent from the thin film, and coagulating the film obtained by the same in a bath containing a nonsolvent or poor solvent for the diblock copolymer. |
