Hierarchical Supramolecular Nanofibers in Meltblown Microfiber Mats for High-Efficiency Filtration
Source abstract
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/m 2 ·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.
