The health-threatening air pollution, especially from particulate matter (PM), has triggered increasing demands for developing low-cost and long-service-life air-cleaning technologies. In the present contribution, a range of high-efficiency textiles/metal-organic framework (MOF) composites (MOFs@textiles) air filters with excellent washable reusability is presented. By processing MOFs onto textile substrates via an eco-friendly solvent-free method to enable the microporous feature and also strong PM adhesion, we develop flexible, highly effective air filters with >95.00% PM removal efficiency (e.g., MiL-53(Al)@Aramid, PM: 95.30%, PM: 96.11%) under harmful air quality conditions (average PM mass concentration > 280 μg m and PM > 360 μg m). Therefore, these MOFs@textiles are promising composites for producing efficient and recyclable out-/indoor air purifiers.
对健康构成威胁的空气污染，尤其是来自颗粒物（PM）的污染，引发了对开发低成本、长使用寿命空气净化技术的需求不断增加。在本论文中，展示了一系列具有出色可洗可重复使用性的高效纺织品/金属有机框架（MOF）复合材料（MOFs@纺织品）空气过滤器。通过一种环保的无溶剂方法将MOFs处理到纺织品基材上，以实现微孔特性以及对PM的强附着力，我们开发出了柔性、高效的空气过滤器，在有害空气质量条件下（平均PM质量浓度>280μg/m且PM>360μg/m），其PM去除效率>95.00%（例如，MiL-53(Al)@芳纶，PM：95.30%，PM：96.11%）。因此，这些MOFs@纺织品是用于生产高效且可回收的室外/室内空气净化器的有前景的复合材料。
