“…The groups of polysaccharides are suitable materials for these environmental issues because of their biobased origins, variety of types, eco-friendly, and renewable nature [78]. In general, the nanofibers have been applied for many environmental problems such as removing pollutants from the air by filtration [79], water treatment [80], antimicrobial treatment [81], environmental sensing [82], for heavy metal removing as adsorbents [83,84], and agricultural/environmental remediation [78,85]. The environmental sustainability of water using cellulose nanofibers-based green nanocomposites is considered one of the most important environmental issues [86].…”

Natural fibers are an important source for producing polymers, which are highly applicable in their nanoform and could be used in very broad fields such as filtration for water/wastewater treatment, biomedicine, food packaging, harvesting, and storage of energy due to their high specific surface area. These natural nanofibers could be mainly produced through plants, animals, and minerals, as well as produced from agricultural wastes. For strengthening these natural fibers, they may reinforce with some substances such as nanomaterials. Natural or biofiber-reinforced bio-composites and nano–bio-composites are considered better than conventional composites. The sustainable application of nanofibers in agricultural sectors is a promising approach and may involve plant protection and its growth through encapsulating many bio-active molecules or agrochemicals (i.e., pesticides, phytohormones, and fertilizers) for smart delivery at the targeted sites. The food industry and processing also are very important applicable fields of nanofibers, particularly food packaging, which may include using nanofibers for active–intelligent food packaging, and food freshness indicators. The removal of pollutants from soil, water, and air is an urgent field for nanofibers due to their high efficiency. Many new approaches or applicable agro-fields for nanofibers are expected in the future, such as using nanofibers as the indicators for CO and NH3. The role of nanofibers in the global fighting against COVID-19 may represent a crucial solution, particularly in producing face masks.

“…Numerous methods have been reported for recycling discarded CFs, such as electrospinning (Kakoria and Sinha-Ray, 2022), solution blow spinning (Tan et al, 2019), and centrifugal spinning (Xia et al, 2022), which are mainly used for air/water ltration (Kim and Park, 2022), heavy metal separation (Gupta et al, 2015), drug delivery (Khoshnevisan et al, 2018), and biosensing. The aforementioned applications show that acetate ber possesses good hydrophilic properties (Xu and Na, 2020) and is biodegradable, providing a functional design for application to high-e ciency and stable solar desalination.…”

Solar steam generation is a promising technology to realize e cient and green desalination with a minimized carbon footprint. Discarded cigarette lters (CFs) cause signi cant harm to the environment but have good recycling potential for solar steam generation. In this study, an e cient thermallypositioned material (AC-CF), which uses renewable cellulose acetate CFs and an acetylene carbon black (AC) coating as an absorber, was developed for application as a solar steam generator. The AC-CF exhibited superhydrophilic characteristics and extensive solar absorption (approximately 100%). These properties enable the resulting AC-CF to exhibit rapid water transport and a strong photothermal conversion ability, with an outstanding evaporation rate of 1.81 kg•m -2 •h -1 under 1 sun illumination. The evaporator can remove most impurities and dye molecules during outdoor operation. Subsequently, the AC-CF evaporator was dissolved and recycled using N, N-dimethylformamide, and the recycling method yielded good results. This method for preparing absorbers reduces manufacturing costs and guides the potential practical application of recycled polymer resources using discarded CFs.

Nanofibers have received extensive attention in the fields of biomedicine, energy catalysis, environmental sciences, and filtration owing to their high specific surface area and controllable porosity. Electrospinning and centrifugal spinning are the two most effective methods for fabricating nanofibers. However, the low preparation efficiency of electrospinning limits the use of that technology in the large-scale production of nanofibers. The morphology of nanofibers prepared by centrifugal spinning is slightly inferior to electrospinning. Centrifugal electrospinning has great industrial application potential. It is a new method for fabricating nanofibers formed by combining centrifugal and electrostatic forces. It can efficiently fabricate nanofibers with good alignment. In particular, the use of polymer melt as the spinning precursor for centrifugal electrospinning can effectively address the problem of solvent residue in the fiber. In this review, the working principle and device used for centrifugal electrospinning is introduced, the influence of different components of the spinning device on the spinning process is discussed, and the effects of spinning parameters on fiber properties are explained. Then, some applications of nanofibers fabricated are described by centrifugal electrospinning in various areas, including energy, biomedicine, and filtration. Finally, the challenges of centrifugal electrospinning are summarized, and a perspective on future research is provided.
