IIIaSelf-assembled structure and membrane comprising block copolymer and process for producing the same by spin coating IIIa

摘要

Disclosed is a self assembled structure formed from a self assembled two-block copolymer of formula (I) (I), Where R ¹ -R ⁴ , n, and m are as described herein, which finds use to produce nanoporous membranes. In embodiments of the self assembled structure, the block copolymer self assembles into a cylindrical shape. Also disclosed is a method of making such a self-assembled structure comprising spin coating a polymer solution containing the two-block copolymer to obtain a thin film, followed by solvent annealing the film. Also disclosed is a method for manufacturing a porous membrane from the self-assembled structure.
