“…The HCHO adsorption by composite gelatin/β–CD nanofibers mats (0.75 mg/g) is better that by polyacrylonitrile/β–CD nanofibers (0.07 mg/g) ( Kadam et al, 2018b ) and β–CD cross-linked textiles (0.06 mg/g) ( Kadam et al, 2020 ). The HCHO adsorption value from this work (0.75 mg/g) is also higher than the 0.12 mg/mg of PAN/β–CD nanofibers ( Noreña-Caro and Álvarez-Láinez, 2016 ). However, it is much less than that of activated carbon fiber (roughly 24 mg/g) ( Rong et al, 2003 ).…”

“…Additionally, electrostatic air cleaners made by HEPA are employed to improve the air‐conditioned indoor spaces by removing dust, pollen, bioaerosols, and volatile organic gases. For example, Noreña‐Caro and Álvarez‐Láinez designed PAN nanofibers functionalized by β‐cyclodextrin for the capture of formaldehyde that may diffuse in newly decorated indoor spaces. The electrospun nanofibrous membranes not only captured the contaminants in the building circulation system but also allowed more air to pass through (low pressure drop), which is required to pump the air through the air filtration media and conserve energy.…”

In modern society, traffic and transportation and the manufacturing industry and construction industries continuously release large amounts of dust and particles into the atmosphere, which can cause heavy air pollution, leading to health hazards. The haze disaster, a serious problem in developing countries such as China and India, has become one of the main issues of global environmental pollution in recent decades. Many air filtration technologies have been developed. Air filtration using electrospun fibers that intercept fine particles/volatile organic gases/bacterium is a relatively new, but highly promising, technique. Due to their interconnected nanoscale pore structures, highly specific surface areas, fine diameters, and porous structure as well as their ability to incorporate active chemistry on a nanoscale surface, electrospun fibers are becoming a promising versatile platform for air filtration. In this review, following a short introduction concerning the need for air filtration and filtration theory and mechanism, electrospun nanofibers membranes for air filtration have been highlighted, including the preparation (electrospinning process) and the parameters relevant to filtration efficacy. Additionally, various types (function) of the electrospun air filtration membranes have been classified in detail. Furthermore, their potential in the filtration of fine particles and chemical pollutants has been discussed. Finally, the challenges of their practical application and the future prospects have been summarized. Given that some advanced electrospun air filtration nanofibrous membranes exist for treating different contaminants from various types of polluted atmosphere, it is believed that they should make a significant contribution in protection against air pollution.

“…Nevertheless, there exist also some studies were the advantages of the binding of CDs to the fibers surface are not so clear. For comparative purposes regarding ability to capture formaldehyde, polyacrylonitrile fibers were prepared either with βCD entrapped in the fibers or with a coating of βCD cross-linked with citric acid [ 101 ]. Compared to fibers prepared without βCD, incorporation of βCD in either form caused an increase in fiber diameter and a decrease in surface area of mats, which was more remarkable in the case of the coating.…”

“…Compared to fibers prepared without βCD, incorporation of βCD in either form caused an increase in fiber diameter and a decrease in surface area of mats, which was more remarkable in the case of the coating. Coated fibers adsorbed less formaldehyde and more slowly than βCD-embedded fibers, which has been ascribed to the role that free hydroxyl groups in βCD may play in the interaction with the guest molecules and also to the less rigid conformation of the non-coated fibers [ 101 ].…”

Cyclodextrins (CDs) can endow electrospun fibers with outstanding performance characteristics that rely on their ability to form inclusion complexes. The inclusion complexes can be blended with electrospinnable polymers or used themselves as main components of electrospun nanofibers. In general, the presence of CDs promotes drug release in aqueous media, but they may also play other roles such as protection of the drug against adverse agents during and after electrospinning, and retention of volatile fragrances or therapeutic agents to be slowly released to the environment. Moreover, fibers prepared with empty CDs appear particularly suitable for affinity separation. The interest for CD-containing nanofibers is exponentially increasing as the scope of applications is widening. The aim of this review is to provide an overview of the state-of-the-art on CD-containing electrospun mats. The information has been classified into three main sections: (i) fibers of mixtures of CDs and polymers, including polypseudorotaxanes and post-functionalization; (ii) fibers of polymer-free CDs; and (iii) fibers of CD-based polymers (namely, polycyclodextrins). Processing conditions and applications are analyzed, including possibilities of development of stimuli-responsive fibers.
