“…Nanofiber mats offer many advantages and have emerged as ideal candidates for suitable and efficient air filtration materials to purify the air. Since they can be effectively and inexpensively manufactured by electrospinning, they offer a promising strategy for efficient air filter materials [ 35 , 36 , 37 ]. According to the results of several research groups, nanofibers can easily be produced by electrospinning process from natural materials, such as polysaccharides, collagen, silk, cellulose, or synthetic polymers, such as polyacrylonitrile (PAN), poly(lactic acid) (PLA), acrylonitrile butadiene styrene (ABS), polyurethane (PU), polyvinyl alcohol (PVA), poly(ethylene glycol) (PEG), polystyrene (PS), polypropylene (PP), polyethylene terephthalate (PET), polyamide-6 (PA-6), etc.…”

Air pollution is one of the biggest health and environmental problems in the world and a huge threat to human health on a global scale. Due to the great impact of respiratory viral infections, chronic obstructive pulmonary disease, lung cancer, asthma, bronchitis, emphysema, lung disease, and heart disease, respiratory allergies are increasing significantly every year. Because of the special properties of electrospun nanofiber mats, e.g., large surface-to-volume ratio and low basis weight, uniform size, and nanoporous structure, nanofiber mats are the preferred choice for use in large-scale air filtration applications. In this review, we summarize the significant studies on electrospun nanofiber mats for filtration applications, present the electrospinning technology, show the structure and mechanism of air filtration. In addition, an overview of current air filtration materials derived from bio- and synthetic polymers and blends is provided. Apart from this, the use of biopolymers in filtration applications is still relatively new and this field is still under-researched. The application areas of air filtration materials are discussed here and future prospects are summarized in conclusion. In order to develop new effective filtration materials, it is necessary to understand the interaction between technology, materials, and filtration mechanisms, and this study was intended to contribute to this effort.

“…Materials' hydrophobicity behaviour is classified into two types involve those that are hydrophilic and hydrophobic 5,6 In contrast to hydrophobic materials, which have self-cleaning surfaces and tend to reject water, hydrophilic materials tend to form hydrogen bonds with water and have a contact angle of less than 90 degrees [7][8][9] . The primary synthesis techniques for nanomaterial-based membranes are phase inversion, sintering, layer-by-layer, interfacial polymerization 10 and electrospinning [10][11] . Recent studies have shown that the electrospinning approach is a flexible and efficient method to create nanofibrous membranes, particularly polymer membranes with controllable compositions and structures [12][13][14] .…”

Polyacrylonitrile (PAN) and Polyamide (PA)-6 based nanofibrous composite were prepared for air filtration application. PAN was electrospun on spun-bonded non-woven polypropylene which acts as a collector and the samples were coated with PA-6. Box-Behnken experimental design was used to design the experimental plan. As per the experimental plan, PA-6 coated samples were treated with different concentrations of an alkali solution (NaOH) (2%, 5% and 8%) and treatment temperature (60oC, 80oC and 100oC) to enhance the surface properties. As prepared nanofibrous composite was tested for its various properties such as surface morphology, particle filtration efficiency and air permeability. Fourier transform infra-red analysis and scanning electron microscope were performed to analyze the functional groups and morphology of the nanofibrous composite respectively. The air permeability of the control and treated samples was analyzed as per the standard procedure and the permeation level varies from 52.5 to 60 cm3/cm2/s for control samples, 65–195 cm3/cm2/s for treated samples. The overall filtration efficiency for treated samples varies from 36.54% to 78.56%. The sample which is treated with 5% NaOH at 60oC has a higher overall filtration efficiency of 78.56%.
