“…The results demonstrate that the performance of the electrospun LSM/YSZ nanofiber cathode strongly depends on its microstructure. 148 Chen et al created hollow nanofibers of PrBa 0.5 Sr 0.5 Co 2 O 5+d (PBSC), and assembled them into a three dimensional (3D) fibrous porous electrode. A solid oxide fuel cell based on this 3D fibrous cathode demonstrates a peak power density of 1.11 W cm À2 at 550 1C when humidified H 2 was used as the fuel and ambient air as the oxidant.…”

“…The microstructure of the as-prepared PEG/PLA films shown in Figure 1 significantly changed due to varying the precursor electrospinning solution. PLA25 and PLA35 PEG/PLA films exhibited typical morphologies for the electrospinning method [23][24][25][26][27][28][29][30][31][32][33][34][35], while the PLA45 PEG/PLA film showed the characteristic electrosprayed microstructure [33][34][35]. For the PLA25 film derived from solution PLA25 with the lowest PLA content of 25 wt.%, the outerdiameter (O.D.)…”

“…The objective of this work is to prepare novel films with high cooling performance, good wetting and adsorption properties, as well as considerable mechanical properties for HNB tobacco application. The electrospinning technique has been considered as one of the most efficient ways to fabricate continuous fibers in the submicron to nanometer scale range, and the microstructure of the fibers is highly dependent on electrospinning parameters such as precursor electrospinning solution, operating voltage and the distance from the collector to the needle [23][24][25][26][27][28][29][30][31][32][33][34][35]. Therefore, in the present work, three typical electrospun/electrosprayed PEG/PLA films with different morphologies were prepared by using the simple electrospinning or electrospray method and adjusting the PLA content and precursor electrospinning solution.…”

Polylactic acid (PLA) film is an alternative filter material for heat-not-burn (HNB) tobacco, but its controllability in cooling performance is limited. In this work, polyethylene glycol (PEG) was introduced to form a polyethylene glycol/polylactic acid (PEG/PLA) film by electrospinning or electrospraying techniques to enhance the cooling performance, due to its lower glass transition and melting temperatures. The PEG/PLA films with typical electrospun or electrosprayed morphologies were successfully fabricated. One typical endothermic peak at approximately 65 °C was clearly observed for the melting PEG phase in the heating process, and the re-crystallization temperature represented by an exothermic peak was effectively lowered to 90–110 °C during the cooling process, indicating that the cooling performance is greatly enhanced by the introduction of the PEG phase. Additionally, the wetting properties and adsorption properties were also intensively studied by characterizing the contact angles, and the as-prepared PEG/PLA films all showed good affinity to water, 1,2-propandiol and triglyceride. Furthermore, the PEG/PLA film with a PLA content of 35 wt.% revealed the largest elasticity modulus of 378.3 ± 68.5 MPa and tensile strength of 10.5 ± 1.1 MPa. The results achieved in this study can guide the development of other filter materials for HNB tobacco application.

Carbonaceous materials originated from electrospinning fibers with hierarchical porosity and good conductivity have attracted intensive attention in the field of electrocatalysis, especially for the oxygen reduction reaction (ORR). Large batches of fibers with uniform sizes can be easily fabricated by electrospinning technology as the precursors of carbon fibers, manifesting the potential to develop a large‐scale, low‐cost, high‐activity ORR catalyst production line for new energy devices such as fuel cells and metal–air batteries. Herein, based on a simple understanding of the ORR mechanism and electrospinning technology, those investigations on synthesizing non‐noble‐metal ORR catalysts through electrospinning in recent years are reviewed. The advantages brought by applying electrospinning technology to the preparation of ORR catalysts are briefly explained. Electrospinning fibers with specific structures for ORR catalysis obtained by innovated spinnerets are displayed. Importantly, the strategies of improving ORR performance for electrospinning fibers through substrate functionalization and active site regulation are discussed in detail. Finally, the prospects and challenges of developing electrospinning technology applied to non‐noble metal ORR electrocatalysis are proposed.
