Volatile organic compounds (VOCs) significantly contribute to atmospheric pollution and present considerable health hazards. This study involves the fabrication of a novel ionic liquid/polymer nanofiber membrane, [P]TMPP/PAN, using electrospinning, and its subsequent evaluation for adsorption performance concerning typical aromatic volatile organic compounds-benzene, toluene, and xylene. The membranes were methodically analysed utilising SEM, TGA, FTIR, and XRD techniques. Adsorption tests indicated that augmenting the [P]TMPP loading improved VOC uptake, with the 80 wt% ionic liquid membrane attaining maximum adsorption capacities of 1466.81, 569.14, and 456.29 mg/g for benzene, toluene, and xylene, respectively-signifying enhancements of 23.6-, 4.8-, and 8.4-fold compared to pristine PAN. Furthermore, regeneration studies validated consistent performance across four adsorption-desorption cycles. The results underscore the efficacy of electrospun [P]TMPP/PAN membranes as reusable adsorbents for the elimination of volatile organic compounds in air purification applications.
挥发性有机化合物（VOCs）对大气污染有显著影响，并带来相当大的健康危害。本研究涉及使用静电纺丝制备一种新型离子液体/聚合物纳米纤维膜[P]TMPP/PAN，并随后对其针对典型芳香族挥发性有机化合物——苯、甲苯和二甲苯的吸附性能进行评估。利用扫描电子显微镜（SEM）、热重分析（TGA）、傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）技术对这些膜进行了系统分析。吸附测试表明，增加[P]TMPP负载量可提高对VOCs的吸收，80 wt%离子液体膜对苯、甲苯和二甲苯的最大吸附容量分别达到1466.81、569.14和456.29 mg/g，与原始PAN相比分别提高了23.6倍、4.8倍和8.4倍。此外，再生研究证实了在四个吸附-解吸循环中性能的一致性。结果强调了静电纺丝[P]TMPP/PAN膜作为可重复使用吸附剂在空气净化应用中消除挥发性有机化合物的有效性。
