Membranes Comprising Self-Assembled Block Copolymers and Process for Preparing Such Membranes by Spin-Coating Method (IIa) |
| abstract |
Membranes formed from self-assembling block copolymers are disclosed, such as diblock copolymers of formula (I): Wherein, R 1 -R 4 , n and m are as described in the present invention, which are used to prepare nanoporous membranes. Embodiments of the membranes contain block copolymers that self-assemble into cylindrical morphologies. Also disclosed are methods of preparing such membranes involving spin coating polymer solutions containing block copolymers to obtain thin films, followed by annealing the films in solvent vapor and/or soaking in solvents or solvent mixtures to form nanoporous membranes. |
