Abstract

Particulate matter pollution presents a critical global health challenge, with fine particles penetrating conventional barriers and contributing to severe respiratory diseases. However, current air filters frequently exhibit significant performance limitations, including poor filtration selectivity, limited breathability, and compromised wearing safety. In this study, a scalable strategy is presented for fabricating high-performance hierarchical filtration materials by incorporating metal–organic supramolecular nanofibers@PLA microfiber melt-blown matrices (MON@PM). The resulting MON@PM filters exhibit outstanding overall performance: high PM_2.5 removal efficiency (99.6%), low pressure drop (39 Pa), superior moisture vapor transmission rate (1472 g/m²·day), and notable bactericidal activity (>99.99% against Escherichia coli and Staphylococcus aureus). This work establishes a pathway for advanced protective materials that simultaneously enhance filtration efficiency, respiratory comfort, and antimicrobial functionality.

熔喷微纤维垫中分层超分子纳米纤维的高效过滤

颗粒物污染是一项重大的全球健康挑战，细颗粒物穿透常规屏障，导致严重的呼吸系统疾病。然而，目前的空气过滤器经常表现出显著的性能限制，包括过滤选择性差，有限的透气性和磨损安全性受损。在这项研究中，提出了一种可扩展的策略，通过结合金属有机超分子nanofibers@PLA微纤维熔喷基质（MON@PM）来制造高性能分层过滤材料。所得MON@PM过滤器整体性能优异：PM2.5去除率高（99.6%），压降低（39 Pa），水汽透过率高（1472 g/m2·天），对大肠杆菌和金黄色葡萄球菌的杀菌活性显著（99.99%）。这项工作为同时提高过滤效率、呼吸舒适性和抗菌功能的先进防护材料开辟了一条途径。
