Abstract

ABSTRACT This study innovatively used polyethylene glycol (PEG) as a multifunctional modifier to prepare nano‐zinc oxide and polyhexamethylene guanidine hydrochloride (Nano ZnO/PHMG) hybrid melt‐blown antibacterial composite materials by twin‐screw blending. PEG overcame traditional additives' single‐function limitation, achieving dual structural regulation and antibacterial enhancement. PEG rheological properties were modulated to produce multistage fiber structures, improving filtration performance, while simultaneously optimizing antibacterial component distribution through its water solubility. Systematic experiments revealed how PEG‐regulated local viscosity affected multistage fiber formation and pore distribution, directly impacting filtration performance. At 12% PEG loading (ABA‐PP‐12PEG), optimal comprehensive performance was demonstrated: 77.45% filtration efficiency (153.5% increased) with 34.0% lower resistance (11.28 Pa). Post‐treatment further enhanced performance to 80.06% efficiency and 10.68 Pa resistance. Antibacterial rates surged 6.7‐fold from 1.78 to 12.01.

高效捕获PM0.3的多功能微/纳米非织造布抗菌性能

摘要：本研究以聚乙二醇（PEG）为多功能改性剂，采用双螺杆共混法制备了纳米氧化锌和聚六亚甲基胍盐酸（nano ZnO/PHMG）熔喷复合抗菌材料。聚乙二醇克服了传统添加剂单一功能的限制，实现了双重结构调节和抗菌增强。通过调节聚乙二醇的流变特性，产生多级纤维结构，提高过滤性能，同时通过其水溶性优化抗菌成分的分布。系统实验揭示了聚乙二醇调节的局部粘度如何影响多级纤维的形成和孔隙分布，直接影响过滤性能。在12%的PEG （ABA‐PP‐12PEG）负载下，最佳综合性能为：过滤效率77.45%（提高153.5%），阻力降低34.0% （11.28 Pa）。后处理进一步将性能提高到80.06%的效率和10.68 Pa的电阻。抗菌率从1.78上升到12.01，上升了6.7倍。

期刊介绍： For more than 30 years, Polymer Engineering & Science has been one of the most highly regarded journals in the field, serving as a forum for authors of treatises on the cutting edge of polymer science and technology. The importance of PE&S is underscored by the frequent rate at which its articles are cited, especially by other publications - literally thousand of times a year. Engineers, researchers, technicians, and academicians worldwide are looking to PE&S for the valuable information they need. There are special issues compiled by distinguished guest editors. These contain proceedings of symposia on such diverse topics as polyblends, mechanics of plastics and polymer welding.
