“…Among many approaches such as molecular technology, biological preparation, and spinning technique, electrospinning is a relatively simple and effective method, and also suitable and compatible with the preparation of nanofiber membranes [9][10][11][12]. Recently, nanofiber membranes have been successfully produced using different polymers by electrospinning for indoor air protection [13,14].…”

Particulate matter is one of the main pollutants, causing hazy days, and it has been serious concern for public health worldwide, particularly in China recently. Quality of outdoor atmosphere with a pollutant emission of PM2.5 is hard to be controlled; but the quality of indoor air could be achieved by using fibrous membrane-based airfiltering devices. Herein, we introduce nanofiber membranes for both indoor and outdoor air protection by electrospun synthesized polyacrylonitrile:TiO 2 and developed polyacrylonitrile-co-polyacrylate:TiO 2 composite nanofiber membranes. In this study, we design both polyacrylonitrile:TiO 2 and polyacrylonitrile-co-polyacrylate:TiO 2 nanofiber membranes with controlling the nanofiber diameter and membrane thickness and enable strong particulate matter adhesion to increase the absorptive performance and by synthesizing the specific microstructure of different layers of nanofiber membranes. Our study shows that the developed polyacrylonitrile-co-polyacrylate: TiO 2 nanofiber membrane achieves highly effective (99.95% removal of PM2.5) under extreme hazy air-quality conditions (PM2.5 mass concentration 1 mg/m 3 ). Moreover, the experimental simulation of the test in 1 cm 3 air storehouse shows that the polyacrylonitrile-co-polyacrylate:TiO 2 nanofiber membrane (1 g/m 2 ) has the excellent PM 2.5 removal efficiency of 99.99% in 30 min.

Four different self-made free surface electrospinning (FSE) devices, namely, modified bubble-electorspinning (MBE) device, modified free surface electorspinning (MFSE) device, oblique section free surface electorspinning (OSFSE) device and spherical section free surface electrospinning (SSFSE) device, were presented to obtain high-throughput preparation of high quality nanofibers in this paper. The preparation mechanisms of these four FSE device were studied by simulating the electric field distribution using Maxwell 3D, due to the importance of electric field in the FSE process. And the effects of them on the morphology and yield of nanofibers were investigated by experiments. The experimental data agreed with the simulation results of electric field, and showed these four FSE device all could be used to prepare high quality nanofibers in large quantities. Meanwhile, comparing the spinning effects of these four FSE device, the results illustrated the SSFSE device was the optimal FSE device because of the highest quality and yield of nanofibers, and its yield could reach 20.03 g/h at the applied voltage of 40 kV.

“…1,2 Electrospun fibers have shown great potential in many applications such as supercapacitors, electrodes, filters, medical devices, and sensors. 3,4 For the huge potential of electrospinning and electrospun fibers, modified electrospinning technologies, such as bubble spinning [5][6][7][8] and centrifugal force spinning, 9,10 have been invented aiming to realize mass production of electrospun fibers. Considering that the weakness of electrospun products has severely hampered the industrialization of electrospinning and its products, enhancement measures such as crosslinking, 11,12 nanoparticle reinforcement, [13][14][15] and post-draw 16 have been introduced to improve the mechanical properties of electrospun fiber mats.…”

Electrospun nanofibers have shown great potential in wide applications such as energy, filtration, medical devices, and sensors. For all these applications, fiber morphology, fiber diameter and pore size of electrospun fiber mat play critical roles in determining the performance of the final products. Research has proved that sonic vibration can dramatically improve the electrospinnability of polymer solutions and subsequently the resultant fiber properties. In this work, the effects of sonic vibration on fiber morphology as well as fiber diameter and the pore structures of electrospun polyacrylonitrile fiber mat were investigated. The relationships between sonic vibration and fiber diameter, and pore size of the electrospun fiber mats were also studied.
