Microporous polyether ether ketone membranes and the preparation thereof |
| abstract |
Microporous polyetheretherketone (PEEK) membranes and hollow fibers are formed without sulfonating the PEEK polymer. A method of making membranes, fibers and articles from solutions of PEEK in non-sulfonating acid solvents is claimed. Solvents include methane sulfonic acid and trifluoromethane sulfonic acid. Sulfuric acid may be used as a diluent in non-sulfonating amounts. PEEK membranes are used as supports for composite ultrafiltration and reverse osmosis membranes. |
