摘要

聚乳酸(PLA)在纳米颗粒物过滤领域展现出广阔的应用前景，但其实际应用受到驻极体性能(指材料储存静电荷的能力)弱、过滤效率不足等问题的限制. 因此，对PLA进行改性以提升其过滤性能具有重要意义. 本研究以PLA静电纺丝纳米纤维膜为基体，通过聚多巴胺(PDA)界面修饰策略，在纤维表面构建具有强黏附性与多重官能团的活性界面层，进而诱导Zn(锌)/Co(钴)双金属有机框架(Zn/Co-MOF)的原位可控生长，最终制备出具有多级微纳结构和显著增大比表面积的双金属MOF功能化静电纺丝纳米纤维膜(BMF-PLA). 该膜呈现出由双金属MOF纳米颗粒均匀锚定于纤维表面所形成的分级粗糙结构与连续三维网络，显著增强了气流传质与颗粒物过滤效率，BMF-PLA对PM

2.5

和PM

0.3

的过滤效率分别高达99.22%和97.65%，使其在空气净化领域具有显著优势. 该研究不仅为PLA滤材的高性能化提供了一种有效可行的表面功能化策略，也为设计开发新一代可持续、高性能空气过滤材料提供了新的思路.

Abstract

Poly(lactic acid) (PLA) fiber membranes demonstrate considerable potential for nanoparticle filtration. However

its practical application is largely limited by weak electret performance and insufficient filtration efficiency. Consequently

modification PLA membranes to enhance the filtration performance is of significant importance. This study utilized electrospun PLA nanofiber membranes as the substrate. By a polydopamine (PDA) interfacial modification strategy

an active layer possessing strong adhesion and multiple functional groups was constructed at PLA fiber surfaces. This layer subsequently induced the

in situ

controllable growth of zinc/cobalt bimetallic-organic frameworks (Zn/Co-MOF)

ultimately yielding a bimetallic MOF-functionalized electrospun nanofibrous membrane (BMF-PLA)

which was characterized by a hierarchical micro/nano structure and a substantially increased specific surface area. The BMF-PLA membrane exhibited a hierarchical roughness structure

formed by bimetallic MOF nanoparticles uniformly anchored onto the fiber surfaces with robust interfacial bonding. This unique structure significantly enhanced airflow flux and particulate matter filtration efficiency. The BMF-PLA membrane achieved high filtration efficiencies of up to 99.22% for PM

2.5

and 97.65% for PM

0.3

appealing for air purification applications. This effort provides an effective and feasible surface functionalization strategy for developing high-performance PLA

filter materials

offering new insights for designing the next-generation

sustainable and high-performance protective membranes.
