“…391 With the use of a mixture of DMF and THF at a weight ratio of 1:1 as the solvent, the water droplets could penetrate into the jet, resulting in the formation of internal pores and the formation of a yarn-like structure (Figure 22C,D). 391 Based on this method, porous nanofibers made of PVDF, 394 poly(ether imide), 395 and PET 396 have also been reported.…”

Electrospinning is a versatile and viable technique for generating ultrathin fibers. Remarkable progress has been made with regard to the development of electrospinning methods and engineering of electrospun nanofibers to suit or enable various applications. We aim to provide a comprehensive overview of electrospinning, including the principle, methods, materials, and applications. We begin with a brief introduction to the early history of electrospinning, followed by discussion of its principle and typical apparatus. We then discuss its renaissance over the past two decades as a powerful technology for the production of nanofibers with diversified compositions, structures, and properties. Afterward, we discuss the applications of electrospun nanofibers, including their use as “smart” mats, filtration membranes, catalytic supports, energy harvesting/conversion/storage components, and photonic and electronic devices, as well as biomedical scaffolds. We highlight the most relevant and recent advances related to the applications of electrospun nanofibers by focusing on the most representative examples. We also offer perspectives on the challenges, opportunities, and new directions for future development. At the end, we discuss approaches to the scale-up production of electrospun nanofibers and briefly discuss various types of commercial products based on electrospun nanofibers that have found widespread use in our everyday life.

“…As one of the most widely used low-cost polymers, poly(ethylene terephthalate) (PET) materials featured with excellent thermal and chemical stability and mechanical performance [1,2,3], have been widely applied to various areas, such as textile fibers, films and engineering plastics [4,5,6]. In recent years, great attention on PET or other polyester fabrics has shifted from single comfort to a health management function, among which antibacterial function is considered to be a critical indicator.…”

The approach of in situ polymerization modification has proven to be an effective route for introducing functions for polyester materials. In this work, Cu2O@ZrP nanosheets with excellent dispersity and high antibacterial activity were integrated into in situ polymerized polyethylene terephthalate (PET) fibers, revealing an enhanced mechanical performance in comparison with the PET fibers fabricated directly via a traditional melt blending method. Additionally, such an in situ polymerized PET/Cu2O@ZrP fibers displayed highly enhanced mechanical properties; and great antibacterial activities against multi-types of bacterium, including S. aureus, E. coli and C. albicans. For the as-obtained two types of PET/Cu2O@ZrP fibers, we have detailed their molecular weight (detailed molecular weight) and dispersibility of nano-Cu2O@ZrP and fibers crystallinity was investigated by Gel chromatography (GPC), Scanning electron microscope (SEM), and X-ray diffractometer (XRD), respectively. The results showed that the aggregation of the nano-Cu2O@ZrP in the resultant PET matrix could be effectively prevented during its in situ polymerization process, hence we attribute its highly enhanced mechanical properties to its superior dispersion of nano-Cu2O@ZrP.

“…As shown in Figure 1b, compared with raw cellulose fibers in Figure 1a, the peaks at 1615 and 1724 cm −1 were the carbonyl stretching of sodium carboxylate (COO−Na + ) and the carbonyl stretching of the carboxylic acid groups (COOH), which proved the successful formation of carboxylate groups after the TEMPO-oxidation process. 31−34 For TOC@LaF 3 :Eu 3+ fibers (Figure 1c), the shift of the CO bond to 1716 cm −1 and the appearance of the absorption peak of the RE−O group at 418 cm −1 verifies that the RE 3+ ions coordinated with ester groups of TOC; 35,36 this kind of interaction makes the structure of the TOC more stable. After surface modification with TiO 2 (Figure 1d), new peaks of Ti−OH at 1630 cm −1 37 and Ti−O around 800 cm −1 38 appeared.…”

A facile and versatile route to fabricate photoluminescent and robust superhydrophobic dual-functional paper was reported. The approach was based on lanthanide-based nanocrystal/nanotitania-doped cellulose fibers with a well-defined micro–nanohierarchical microstructure. Specifically, the cellulose fibers were first treated with the process of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) oxidation. The treated cellulose was then used as a template for the surface chemical deposition of rare-earth ions and subsequent hydrolysis reaction of tetraethyl titanate forming lanthanide-based nanocrystal/nanotitania-doped cellulose fibers. After paper-making and hydrophobicity treatment, the obtained paper possessed excellent luminescence, superhydrophobic, and self-cleaning properties. This synthesis route designed here has the advantages of mass production of biobased photoluminescent materials for anticounterfeiting applications.
