Functionalized electrospun nanofibers for high efficiency removal of particulate matter

Abstract

In recent years, introducing electrospun airfilters to enhance the removal of PM2.5 and PM10–2.5 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 PM2.5 and PM10–2.5 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 PM2.5 and PM10–2.5 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 PM2.5 and PM10–2.5 removal efficiencies of 99.25% and 99.29%, respectively. Hence, the study proved.

Metal–Organic Framework@Graphene Oxide Composite-Incorporated Polyacrylonitrile Nanofibrous Filters for Highly Efficient Particulate Matter Removal and Breath Monitoring

“…However, increasing the MOF@GO content in PAN nanofibers may reduce the tensile strength of the nanofibrous filters due to the possible aggregation of MOF@GO nanocomposites. The dispersion microstructure of nanoparticles plays a major role in the reinforcement of electrospun nanofibrous mats . The results of the mechanical investigation revealed that the developed PAN/MOF@GO nanofibrous filter exhibits reasonable mechanical properties that are required for air filter applications.…”

Application of Electrospun Water-Soluble Synthetic Polymers for Multifunctional Air Filters and Face Masks

“…The authors suggested that this could be attributed to the hydrophilic nature of the tea leaf extract and the formation of a hydrogen bond between TLE and PVA. Therefore, a durability test of FNA has been performed, revealing a high durability of FNA after 10 hrs [76]. Jaski et al (2022) have recently reported the fabrication of a zein-based nanofiber material using two kinds of PVA with the alcoholysis degree of 98-99% and 87-89% as auxiliary spinning polymers.…”

Formation of Three‐Dimensional Polysuccinimide Electrospun Fiber Meshes Induced by the Combination of CaCl2 and Humidity

“…Electrospinning is one of the most versatile and flexible fiberforming techniques that can be used in various fields such as DOI: 10.1002/marc.202300625 tissue engineering, biosensors, air filtration, wound dressings, or drug delivery. [1][2][3][4][5] Since scientific knowledge has drastically increased over the last decades, electrospun fibers can be produced with different physical and chemical structures in a wide range of diameters. Besides, new types of electrospinning equipment have also been developed at an industrial scale which further widened the possible application of electrospun meshes.…”
