“…Furthermore, it is possible to selectively produce and control the pore size between the nanofibers according to the application definition. In addition, by introducing the antimicrobial agents and particles and changing the morphology of the nanofiber mats into the nanoscale, well-cross-linked pore structure, all the conditions required for trapping fine particles can be met [ 28 , 29 , 30 , 31 , 32 ].…”

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.

“…By structural design with modifications on spinnerets and collectors, functional electrospun fibers with special structures Janus, core-shell, hollow, porous, helical, etc., are comprehensively investigated. Such functional electrospun fibers have been widely used in different fields, such as masks (26,27), stimuli-responsive materials and actuators (28)(29)(30)(31), separation and filtration (32)(33)(34)(35)(36)(37)(38)(39), reinforcements (40)(41)(42)(43)(44)(45), wearable electronics (46)(47)(48)(49)(50), sponges/aerogels (51)(52)(53)(54)(55)(56), tissue engineering (57,58), detection metal ions (59)(60)(61), energy storage (62)(63)(64)(65)(66), catalysts (67)(68)(69)(70)(71)(72)…”

Electrospinning as one of the most versatile technologies have attracted a lot of scientists’ interests in past decades due to its great diversity of fabricating nanofibers featuring high aspect ratio, large specific surface area, flexibility, structural abundance, and surface functionality. Remarkable progress has been made in terms of the versatile structures of electrospun fibers and great functionalities to enable a broad spectrum of applications. In this article, the electrospun fibers with different structures and their applications are reviewed. First, several kinds of electrospun fibers with different structures are presented. Then the applications of various structural electrospun fibers in different fields, including catalysis, drug release, batteries, and supercapacitors, are reviewed. Finally, the application prospect and main challenges of electrospun fibers are discussed. We hope that this review will provide readers with a comprehensive understanding of the structural design and applications of electrospun fibers in different fields.

“…Disposal of oily wastewater through a practical, economic, and feasible strategy is becoming urgent to address increasing contamination from petroleum and crude oil-related industries. [36,37] Previously, ZIF-8 has been utilized as a functional nanocoating to increase the hydrophobicity of porous materials. [38] Therefore, this study explored the surface wettability of the as-prepared amyloid fibrils/ZIF-8 hybrid aerogel, which exhibited a contact angle of 115.2° (Figure 4a).…”

Design and fabrication of versatile adsorbents for universal water purification following green chemistry principles remain challenging. Here, it is shown that amyloid fibrils from protein waste can be used as a functional scaffold for metal organic framework (MOF) biomimetic mineralization. The resulting amyloid fibrils/ZIF‐8 hybrid aerogels can effectively remove nine different heavy metal ions from water due to their hierarchical porous structure. Importantly, amyloid fibrils/ZIF‐8 hybrid aerogels can efficiently remove Hg2+ and Pb2+ from water over five consecutive adsorption–regeneration cycles. Furthermore, a dual removal pathway of adsorption and catalytic degradation is observed in the synthetic dyes, indicating that the aerogel preserves its porous nature and maintains the integrity of versatile functional ligands within ZIF‐8. Finally, it is shown that these hybrid aerogels can also perform successfully in oil–water separation. Considering the facile synthesis procedure, high removal efficiency, affordable cost, and regeneration possibilities, the amyloid fibrils/ZIF‐8 hybrid aerogel stands as an ideal candidate for addressing open challenges in wastewater treatment and water purification.
