In recent years, introducing electrospun airfilters to enhance the removal of PM and PM has received much interest. In this study, a novel poly-(vinyl) alcohol (PVA)/carbon nanoparticle (CNP)/tea leaf extract (TLE), functionalized nanofibrous air filter (FNA) was fabricated using an electrospinning method. Novelty of the unique work in the blending of CNP and TLE, first of its kind, for the preparation of FNA. Polysaccharide crosslinked FNA has a carbon complex with two monosaccharide units to produce the intrinsic properties of the PM and PM removal efficiency. The FNA had promising traits of UV protection. The prepared FNA was characterized using physicochemical, mechanical, antimicrobial activity, etc., in addition to its PM and PM removal efficiency. Pore size and distribution study using the capillary flow porometry method has proved the structure of FNA. FNA exhibited excellent low pressure drop (110 Pa), which are promising characteristics for air purification. FNA from PVA: CNP: TLE exhibited high PM and PM removal efficiencies of 99.25% and 99.29%, respectively. Hence, the study proved.

近年来，引入静电纺丝空气过滤器来增强 PM 和 PM 的去除引起了广泛关注。在这项研究中，采用静电纺丝方法制备了一种新型的聚（聚乙烯醇）（PVA）/碳纳米粒子（CNP）/茶叶提取物（TLE）功能化纳米纤维空气过滤器（FNA）。这种独特的工作的新颖之处在于首次将 CNP 和 TLE 混合用于制备 FNA。多糖交联的 FNA 具有与两个单糖单元交联的碳复合物，从而产生内在的 PM 和 PM 去除效率特性。FNA 具有有前景的抗紫外线特性。除了 PM 和 PM 去除效率外，还使用物理化学、机械、抗菌活性等方法对制备的 FNA 进行了表征。使用毛细流动孔隙率法进行的孔径大小和分布研究证明了 FNA 的结构。FNA 表现出出色的低压降（110 Pa），这是空气净化的有前途的特性。PVA：CNP：TLE 的 FNA 分别表现出 99.25%和 99.29%的高 PM 和 PM 去除效率。因此，该研究证明了这一点。
