Poly(vinylidene fluoride)(PVDF)-Based Nanofibrous Membranes with High Filtration Performance and Durability for Reusable Air Filters |
| 초록 |
We report a strategy that utilizes superhydrophobic poly(vinylidene fluoride)(PVDF) nanofibrous membranes to achieve reusable air filters with high filtration performance and durability. We demonstrate that the additional assembly of nanosized texture on an electrospun PVDF membrane and subsequent low-surface-energy treatment enables nonwetting of various probing liquids. Hence, this makes fine dust particles adsorbed on the modified PVDF membrane to be easily removed by washing and the membrane to exhibit a low roll-off angle (∼15°) even for 1 μL of artificial saliva droplets. Moreover, these modified PVDF membranes are chemically stable, suppressing bacterial suspension adhesion and any bacteria grown to be effectively sterilized via ethanol treatment with no noticeable alteration in the structure. Furthermore, by applying this modified PVDF membrane as a skin layer, we demonstrate that reusable air filters with high filtration performance and mechanical strength can be achieved. |
