Dual component bi-layer electrospun nanofiber membrane for multiple phase liquid separation |
| 초록 |
Materials with selective interfacial activity dominates the industrial and environmental liquid separation application. Existing liquid separation techniques are influenced by chemical and physical modification to tune the membranes’ surface energy. Herein we demonstrate a new separating material influenced by the concept of using liquid to oppose immiscible contacting liquid, a liquid infused electrospun dual-component bilayer nanofiber membrane (DCNM) was scrutinized. A uniform over layer interface was established to repel other immiscible liquids. The DCNM was fabricated by electrospinning hydrophobic polymer polyvinylidene fluoride-co-hexafluoropropylene (PVDF-hfp) on top of the electrospun hydrophilic polymer polyacrylonitrile (PAN). The thickness of each layer was varied and by varying the polymer deposition of the DCNM. The property of the infused liquid was used to regulate the membrane’s interface wettability which is a viable characteristic for multiphase liquid separation. |
