Disclosed are self-assembled structures formed from a self-assembling diblock copolymer of the formula (I):
wherein R 1 -R 4 , n, and m are as described herein, which find use in preparing porous membranes. In an embodiment, the diblock copolymer is present in the self-assembled structures in a cylindrical morphology. Also disclosed is a method of preparing a self-assembled structure, which involves spin coating a polymer solution containing the diblock copolymer to obtain a thin film, followed by solvent annealing of the film. |
