Abstract
Disclosed are treated mixed matrix polymeric membranes comprising a plurality of metal-organic frameworks (MOFs) and a polymeric matrix, wherein the plurality of MOFs are attached to the polymeric matrix through covalent or hydrogen bonds or Van der Waals interaction. The membranes can be treated with plasma, electromagnetic radiation, or thermal energy or any combination thereof.
Claims20
A treated mixed matrix polymeric membrane comprising a polymeric matrix and a plurality of at least a first metal-organic framework (MOF), wherein the plurality of the first MOFs are attached to the polymeric matrix through covalent bonds formed between a functional group from the MOFs and a reactive group from the polymers of the polymeric matrix, wherein the polymeric matrix comprises a polymer of intrinsic microporosity (PIM), or a blend of at least two of PIM and a polyimide polymer, and/or a polyetherimide polymer, and wherein the polymeric membrane has been plasma-treated, treated with electromagnetic radiation, or thermally-treated.
