Self-powered nanogenerators composed of poly(vinylidene fluoride) (PVDF) have received much attention. Solution blow spinning (SBS) is a neoteric process for preparing nanofiber mats with high efficiency and safely, and SBS is a mature fiber-forming technology that offers many advantages over conventional electrospinning methods. Herein, we adopted the SBS method to prepare independent PVDF nanofiber membranes (NFMs), and successfully employed them as nanogenerators. Finally, we tested the change in the output current caused by mechanical compression and stretching, and studied its durability and robustness by charging the capacitor, which can drive tiny electronic devices. The results show that the PVDF nanogenerators by using this SBS equipment can not only be used in wearable electronic textiles, but are also suitable for potential applications in micro-energy harvesting equipment.Keywords:solution blow spinning;micro-energy harvesting;nanogenerators

Functional materials that can quickly absorb and degrade mustard gas are essential for chemical warfare emergency response kits. In this study, a fiber membrane with excellent adsorption and catalytic degradation activity was developed by solution blow spinning polystyrene (PS)/polyurethane (PU) and hydrothermal in situ growth of a zirconium-based MOF (MOF-808). The mechanical properties of the PS/PU fibers were improved by adding a trimethylolpropane tris (2-methyl-1-aziridine propionate) (TTMA) cross-linking agent. Moreover, the C═O bonds in TTMA provided abundant growth sites for MOF-808 in the hydrothermal process, thereby greatly increasing the loading capacity. The fiber surface was completely covered with the MOF-808 particles within 24 h. The PS/PU/TTMA/MOF-808 fiber membrane was used for the catalytic degradation of 2-chloroethyl ethyl sulfide (CEES). The degradation efficiency reached 97.7% after 72 h, indicating its great application potential in emergency wiping cloths for mustard gas adsorption and degradation.

Gelatin (GA) is a natural protein widely used in food packaging, but its fabricated fibrous film has the defects of a high tendency to swell and inferior mechanical properties. In this work, a novel spinning technique, solution blow spinning (SBS), was used for the rapid fabrication of nanofiber materials; meanwhile, nylon 66 (PA66) was used to improve the mechanical properties and the ability to resist dissolution of gelatin films. Morphology observations show that GA/PA66 composite films had nano-diameter from 172.3 to 322.1 nm. Fourier transform infrared spectroscopy and X-ray indicate that GA and PA66 had strong interaction by hydrogen bonding. Mechanical tests show the elongation at break of the composite film increased substantially from 7.98% to 30.36%, and the tensile strength of the composite film increased from 0.03 MPa up to 1.42 MPa, which indicate that the composite films had the highest mechanical strength. Water vapor permeability analysis shows lower water vapor permeability of 9.93 g mm/m2h kPa, indicates that GA/PA66 film’s water vapor barrier performance was improved. Solvent resistance analysis indicates that PA66 could effectively improve the ability of GA to resist dissolution. This work indicates that SBS has great promise for rapid preparation of nanofibrous film for food packaging, and PA66 can be applied to the modification of gelatin film.Keywords:solution blow spinning;gelatin;nylon 66;modification;rapid fabrication

In this work, a nylon 6 nanofibrous membrane was prepared via solution blowing technology and followed hot-press as scaffold for nanofiltration. The structure and properties of the hot-pressed nylon 6 nanofibrous membrane (HNM) were studied the effect of hot-pressing parameters and areal densities. Then an ultra-thin polyamide (PA) active layer was prepared by interfacial polymerization on HNM. The effects of nanofibrous scaffolds on the surface properties of ultra-thin nanofiltration membranes and their filtration performance were studied. Results showed that the nylon 6 nanofibers prepared at a concentration of 15 wt % had a good morphology and diameter distribution and the nanofibers were stacked more tightly and significantly reduced in diameter after hot pressing at 180 °C under the pressure of 15 MPa for 10 s. When the porous scaffold was prepared, HNM with an areal density of 9.4 and 14.1 g/m2has a better apparent structure, a smaller pore size, a higher porosity and a greater strength. At the same time, different areal densities of HNM have an important influence on the preparation and properties of nanofiltration membranes. With the increase of areal density, the uniformity of HNM increased while their surface roughness and pore size decreased, which is beneficial to the establishment of PA barrier layer. With areal density of 9.4 and 14.1 g/m2, the as-prepared nanofiltration membrane has a smoother surface and more outstanding filtration performance. The pure water flux is 13.1 L m−2h−1and the filtration efficiencies for NaCl and Na2SO4are 81.3% and 85.1%, respectively.Keywords:solution blowing;nylon 6 nanofibrous membrane;scaffold;nanofiltration

High-performance TiO 2 nanotube materials are highly demanded across various fields spanning thermal insulation, catalyst supports, filtration, and so on. However, the practical applications of hollow nanotubes are constrained by the low efficiency and uncontrollable structural properties. Herein, mass production of flexible and high catalytic hollow Al/Si@TiO 2 nanotubes were realized. Through solution blow spinning and atomic layer deposition processes, TiO 2 coated Al/Si@PAN core–shell nanofiber intermediate product was obtained with high efficiency. Hollow tubular structure of Al/Si@TiO 2 nanotubes with wall thicknesses among 150–350 nm was successfully replicated by sacrificing PAN core fibers template through a high-temperature pyrolysis process. Organic polysiloxane and polyalumina were employed as the internal supports to enhance the toughness and elasticity of the hollow Al/Si@TiO 2 nanotube products. Diameters of hollow Al/Si@TiO 2 nanotubes can be controlled ranging from 0.5-2.5 μm through adjusting the flow rate among 10–30 mL/h and air pressure among 0.2–0.4 MPa. Pyrolyzed hollow Al/Si@TiO 2 nanotubes exhibited remarkable elasticity with the compression strain of over 60 %. Hollow Al/Si@TiO 2 nanotubes demonstrated a methylene blue degradation efficiency of reached 61 % and outstanding reusability over multiple cycles, which held promising potential for utilization in high efficiency purification and remediation of water pollutants.

Superhydrophobic composite nanofibrous membranes(PP) were prepared from polycaprolactone (PCL)/polystyrene (PS) through solution blow spinning with an airbrush for oil adsorption. PP membranes were characterized by fourier transform infrared spectroscopy, scanning electron microscopy, water contact angle, X-ray Photoelectron Spectroscopy, X-ray diffractometer, and thermogravimetric analysis instrument. The effects of mass ratio of PCL and PS on the morphology, porosity, density, cyrstallinity, thermal stability, and oil adsorption ability were investigated. PP membranes had higher density than PCL and PS, while better hydrophobicity. The saturation adsorption capacity of PP to peanut oil, motor oil, and diesel oil is 16.89 g/g, 20.33 g/g, and 12.17 g/g, respectively. After 6 cycles of reutilization, the adsorption capacity to peanut oil, motor oil, and diesel oil remained at 6.16, 7.46, and 5.33 g/g, respectively, higher than that of pure PCL membrane.The water/oil adsorption selectivity of PP was about 7:100. PP had higher oil adsorption capacities and better water/oil adsorption selectivity than the commercial oil absorbent polypropylene. PP membrane could be prepared and used in situ to separate oil from oil/water mixture. POLYM. ENG. SCI., 59:E171–E181, 2019. © 2018 Society of Plastics Engineers

Polystyrene (PS) dissolved in dichloromethane was spun to prepare the nanofibrous polystyrene membranes (NPS) through solution blow spinning with a commercialized airbrush. The influences of spinning conditions on the membrane morphology, density, and porosity were investigated. Through varying the PS concentration (8%, 9%, 10%), gas pressure (0.1, 0.2, 0.3 MPa), and acceptance distance (10, 12, 15, 18 cm), NPS with diameters of 200–1400 nm were prepared. The membranes had high porosity of 83.9%, and super-hydrophobic and super-oleophilic surface. The oil absorbency to motor oil, peanut oil, diesel oil, and heavy oil was 29.35, 27.27, 21.81, and 22.80 g/g, respectively, while that of the commercialized nonwoven polypropylene was 9.34, 9.17, 7.09, and 7.79 g/g, respectively. NPS could separate oil from water surface in several seconds. It was easy to prepare the membrane in situ on the surface of an oil/water mixture and remove the oil while peeling off the membrane, indicating NPS is potential as oil recovery material in large-area oil pollution environment.

We report a facile strategy for preparing ultralight, mechanically robust, and washable heat-retaining materials via solution blow spinning technology and thermal crosslinking. Fluffy microfibrous assemblies with nonwoven structure were fabricated by blending fibers of stiff and soft polymers and creating a bonding architecture among them. The premise of this design is that polystyrene, which is stiff, can endow materials with rigidity, while thermoplastic polyurethane, which is soft, can absorb energy during mechanical deformation. Moreover, the stability of the sponge was improved by using tris (2-methyl-1-aziridine propionate; TTMA) as a crosslinking agent. The optimized microfibrous sponges present excellent mechanical properties with a large breaking elongation of 42.1% and outstanding resilience in resisting 100 cyclic compressions at 40% strain. Furthermore, the microfibrous sponges exhibit a low volume density of 33.32 mg/cm3, effective heat-preservation ability (low thermal conductivity: 23.1 mW/m·K) and excellent washability. The preparation of microfibrous sponges via solution blow spinning can be a novel route for developing ultralight and superelastic heat retention materials.

Large-scale spinning of high-performance SiO2 porous nanofibers remains a pivotal challenge in facilitating their utilization for flexible thermal insulation purposes. Herein, massive spinning of SiO2 porous nanofibers was achieved through the solution blow spinning (SBS) process utilizing microemulsion polysiloxane solutions. Using MK siloxane polymer as the Si source, a solution characterized by high purity and excellent uniformity was obtained. Multicomponent spinnable microemulsion precursor was prepared by incorporating paraffin as the sacrificial phase, Span 80 and Tween 80 as surfactants, and polyvinylpyrrolidone as the spinning aid. Through optimization of the spinnable solution composition and SBS process parameters, high-speed spinning of paraffin/MK precursor nanofibers was accomplished with a rate of 20 mL·h–1. Subsequent high-temperature pyrolysis facilitated the conversion of organic paraffin/MK nanofibers into SiO2 nanofibers with controllable pores structure. Porous SiO2 nanofiber sponges fabricated using the microemulsion SBS technique exhibit distinctive lightweight and thermal insulation properties [0.037 W·(m·K)−1]. These properties promise to facilitate massive spinning of high-performance inorganic fiber sponges for applications in high-temperature thermal management.

In this work, we compared Bi 2 Sr 2 CaCu 2 O 8+θ (BSCCO) superconducting nanofibers prepared by electrospinning (ES) and solution blowing spinning (SBS) techniques for the first time. The differences in microstructure and magnetic properties of BSCCO superconducting fibers prepared by ES and SBS were investigated. The thickness of the ES-BSCCO nanofibers was more uniform than that of the SBS-BSCCO nanofibers. In addition, the superconducting transition temperature of superconducting SBS-BSCCO nanofibers was only 73.5 K due to the weak connection of grains, which was lower than 82.5 K of the ES-BSCCO sample. Further studies showed the area enclosed by the hysteresis loop, the critical current density, and the intensity of the pinning force of SBS-BSCCO fibers were all smaller than those of the ES-BSCCO sample. Finally, we found that the pinning mechanism of these two BSCCO samples could be ascribed to the activation of the point-pinning mechanism and surface-pinning mechanism.

Polymer templates are critical in the preparation of ceramic fibers from precursor solutions, but the available options are limited. Here, ZrO 2 nanofiber films and aerogels are developed by solution blow spinning method using hydroxypropyl methylcellulose (HPMC) and polyvinylpyrrolidone (PVP) as templates. The effects of HPMC ratio, polymer concentration, and calcination temperature on the morphology and structure of the ZrO 2 nanofibers are investigated. The nanofiber films with an areal density of 20 mg cm −2 exhibit excellent filtration property, achieving a filtration efficiency of 94.94% and a pressure drop of 136 Pa at an airflow velocity of 32 L min −1 . The nanofiber aerogels display low density of 50 mg cm −3 , low thermal conductivity of 0.039 W m −1 K −1 , as well as superior compressibility, demonstrating significant potential for thermal protection applications. This work expands the formation template option of ceramic fibers, offering significant guidance in the development of flexible, high-temperature-resistant ceramic fiber materials.

Bio-based flame retardants are of great significance for ecological environments, sustainable development and human health. Herein, a novel DOPO-based furan-containing flame retardant (FAD) was successfully prepared by DOPO and bio-based compounds (furfural and furfurylamine) via the Schiff base-addition reaction. Subsequently, flame-retardant nonwoven materials with excellent thermal stability, flame retardancy, and carbonization performance were obtained by solution blow spinning technology. The thermal stability and flame-retardant property of the original PLA nonwoven material and the flame-retardant PLA nonwoven materials were analyzed by TGA, LOI, UL-94 flammability tests, and cone calorimetry. Compared to the original PLA nonwoven material, the flame-retardant nonwoven materials showed significantly improved flame-retardant properties. When the addition amount of the flame retardant FAD was 10% (P-FAD-10), the LOI of P-FAD-10 significantly reached 31%, and the peak heat release rate (PHRR) and total heat release (THR) decreased by 14.9% and 21.4%, respectively, compared to the original PLA nonwoven material. Additionally, P-FAD-10 passed the UL-94 V-0 rating with better anti-dripping. This novel P and N-containing bio-based flame retardant FAD and its flame-retardant PLA nonwoven material provide a green and efficient solution for developing high-performance, bio-based flame-retardant nonwoven materials.
