Investigation of metal coated PTFE membrane for controlled ion transportation |
| 초록 |
Functional polymer membrane has been highlighted due to its higher functionality in separation processes for liquid and gaseous mixtures (gas separation, reverse osmosis, nano/micro/ultra filtrations) and in other important applications of membranes, such as bio-materials, catalysis production. In this study, sputtered Pt film was coated on PTFE membrane surface. The Ti film was inserted for improved adhesion between Pt film and PTFE membrane. Under negative electrical bias, the Pt film coated PTFE membrane showed above 30% reduction of Cl- ions in NaCl solution. Selective ion transportation through Pt film coated PTFE membrane under electrical bias will be systemically investigated. |
