Particulate matter (PM) in air pollution is becoming a serious environmental threat to public health globally. The removal of PM, particularly the most harmful PM2.5, is a great challenge for industrialized countries. Hybrid polymer materials have extensive applications in many areas. Herein, types of hybrid polymers obtained from lanthanide ionic liquids and polyvinyl pyrrolidone have excellent PM adsorption capacity especially for PM2.5. The highest adsorption efficiency can exceed 99% for both PM2.5 and PM10. The removal efficiency of PM can be maintained above 90% for 15 h, which can be recycled more than five times without the decline of adsorption efficiency. An introduced luminescent lanthanide can be used to survey the adsorption process by the change of fluorescence intensity. After simple treatment, the PM adsorption capacity of the hybrid polymer can be recovered to be similar with the new one. Besides, the hybrid polymers have favorable thermal stability to adapt to different working conditions. Therefore, the hybrid polymers have potential applications in a high‐efficiency and environmental friendly PM removal filter.

可再生的镧系离子液体/聚合物复合材料，可高效吸附颗粒物

空气污染中的颗粒物（PM）正在全球范围内对公共卫生构成严重的环境威胁。对于工业化国家而言，去除PM（尤其是最有害的PM2.5）是一项巨大的挑战。杂化聚合物材料在许多领域都有广泛的应用。在本文中，由镧系离子液体和聚乙烯吡咯烷酮获得的杂化聚合物的类型具有优异的PM吸附能力，尤其是对于PM2.5。PM2.5和PM10的最高吸附效率都可以超过99％。可以将PM的去除效率保持在90％以上，持续15小时，可以重复使用五次以上而不会降低吸附效率。引入的发光镧系元素可用于通过荧光强度的变化调查吸附过程。经过简单的治疗，杂化聚合物的PM吸附能力可以恢复到与新的相似。此外，杂化聚合物具有良好的热稳定性以适应不同的工作条件。因此，杂化聚合物在高效和环保型PM去除过滤器中具有潜在的应用。
