Method for preparing nanoporous polysulfone-based polymers |
| abstract |
The present invention relates to a method for preparing nanoporous polysulfone-based polymers, including: a copolymer of a polysulfone polymer and a polar polymer is immersed into a compound swelling agent, and maintained for at least 1 minute above room temperature; the compound swelling agent is a “solvent pair” composed of the mixture of solvent A and solvent B; the solvent A has high affinity with the polysulfone polymer; and the solvent B has high affinity with the polar polymer; the treated copolymer is taken out from the compound swelling agent and then dried to remove the solvent to obtain the nanoporous polysulfone-based polymers. |
