  • 摘要: 聚乳酸(PLA)由于其生物可降解性在空气过滤领域具有良好的应用前景,但因其自身较低的电活性以及受到高湿度环境的影响,致使过滤效率不高。为此,采用微波辅助法合成了结构规整、极小尺寸(~500 nm)的金属有机框架MOF-5,进而通过静电纺丝-喷雾技术将不同负载量的MOF-5锚定于PLA纤维表面(PLA/MOF)。在负载量为8wt%时,介电常数和表面电势分别是纯PLA纳米纤维膜(纳纤膜)的2.3倍和3倍,PLA/MOF纳纤膜的电活性显著提升,摩擦电输出电压可达65.8 V。与纯PLA纳纤膜相比,PLA/MOF纳纤膜对PM0.3过滤效率大幅提高,均可达到96%以上。在高湿环境(RH=90%),空气流速为85 L/min时,8wt%负载量的PLA/MOF纳纤膜的过滤效率也可达到90%以上。这种基于提高PLA电活性的MOF化纳纤膜在高湿度环境下滤除PM0.3等人体呼吸安全领域具有广阔应用前景。
