Membrane comprising self-assembled block copolymer and process for producing the same by spin coating |
abstract |
Disclosed are membranes formed from self-assembling block copolymers, for example, diblock copolymers of the formula (I):n nwherein R 1 -R 4 , n, and m are as described herein, which find use in preparing nanoporous membranes. Embodiments of the membranes contain a block copolymer that self-assembles into a cylindrical moiphology. Also disclosed is a method of preparing such membrane which involves spin coating a polymer solution containing the block copolymer to obtain a thin film, followed by annealing the thin film in a solvent vapor and/or soaking in a solvent or mixture of solvents to form a nanoporous membrane. |
