dc.description.abstract | Air pollution, particularly from particulate matters (PMs), has become a serious global issue. Thus, there are increasing demands for improving PM filtering systems for public safety. Here, we have first demonstrated that the surface hydration of electrospun fiber-based filters significantly improves capturing ability of ultrafine PM0.3 (PMs having a diameter of ~ 0.3 mu m). Aluminum-based metal-organic framework (MOF)-303, which is uniformly coated on the surface of polyimide nanofibers (PI NFs), provides sufficient surface hydration with PI NFs due to its high-water uptake capability, resulting in favorable trapping sites for polar molecules or particles in the air. Furthermore, the MOF-303-coated PI NF (PI@MOF-303) filters show relatively low pressure drops, which can be attributed to increasing fiber diameters after MOF-303 coating, resulting from enlarged spaces between fibers. Consequently, the PI@MOF-303 filters afford highly efficient PM0.3 removal properties (95.70%) and low pressure drop (delta P = 36.73 Pa). Our strategy offers new insights into the fabrication of high-performance electrospun fiber-based filters with desirable properties for filtering PMs. | - |
