HYDROPHOBIC MEMBRANE MATERIALS FOR FILTER VENTING APPLICATIONS |
| 摘要 |
The present invention relates to filtration media having hydrophobic (water- repellent) properties. The filtration media are produced using a fluorothermoplastic material, such as a terpolymer of tetrafluoroethylene, vinylidene fluoride, and hexafluoropropylene. The invention also relates to methods of preparing such filtration media using casting solution phase inversion.
