“…For example, silica fibers were obtained by electrospinning an aged sol−gel solution with an optimal viscosity. 128 In another study, ZrP fibers were obtained using a reactive coaxial electrospinning approach, 296 in which a zirconium precursor and a phosphorus source were electrospun together from separate solutions using a coaxial spinneret. The reaction between the zirconium and phosphorus sources was initiated at the interface in the core−sheath fibers to delay the formation of ZrP gel.…”

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.

“…For a given EW more TFE units are present in the backbone of the sort side chain compared to its LSC analogs, providing a higher degree of crystallinity, thereby improving the resistance to swelling in water [65,146,[166][167][168][169][170][171][172][173][174][175][176][177][178][179]. Membranes possessing high proton conductivity at lower RH at elevated temperatures are currently the focus of a lot of research.…”

“…Adding inorganic fillers into the polymer matrix can improve the hygroscopicity and mechanical strength of the membrane, the hydrogen crossover and even the proton conductivity. For instance, zeolites such as NaA zeolite, ETS-10, umbite, mordenite, analcime, faujasite, b-zeolite, ZrP-modified zeolite, and H-type of b-zeolite [8][9][10][11][12][13]; inorganic oxides such as TiO 2 , SiO 2 , ZrO 2 , and ZrO 2 /SO 4 2-[8, [14][15][16][17][18][19][20][21][22][23][24]; and montmorillonite, laponite, sepiolite, and halloysite [8,9,[25][26][27][28][29][30][31][32][33] have been studied for long time.…”

Aquivion membrane displays improved properties as compared to Nafion membrane, partly due to shorter side chains. However, some improvements are still necessary for proton exchange membrane fuel cell to operate at low relative humidity. To overcome this drawback, the addition of clay nanoparticle into the Aquivion matrix can be considered. In this study, different composite mem-branes have been prepared mixing short-side-chain PFSA (perfluorosulfonic acid) Aquivion and selectively modified halloysite nanotubes for PEMFC low relative humidity operation. Halloysites were grafted with fluorinated groups, sulfonated groups, or perfluoro-sulfonated groups on inner or outer surface of the tubes. The obtained composite membranes showed improved properties, especially higher water uptake associated with reduced swelling and better mechanical strength compared to pristine Aquivion membrane and commer-cially available Nafion HP used as reference. The best performance in this study was obtained with Aquivion loaded with 5 wt% of pretreated perfluoro-sul-fonated halloysite. The composite membrane, referred to as Aq/pHNT-SF5, displayed the largest water uptake and proton conductivity among the panel of membranes tested. The chemical stability was not affected by the presence of halloysite in the Aquivion matrix.
