“…86–88 Y–Ba–Cu–O oxide ceramic fibers were fabricated for use in superconducting applications. 89 Ceramic nanofibers of TiO 2 and ZnO with high surface area have been fabricated using SBS from a mixture of Ti or Zn sources and polymer in solution, followed by postprocessing. 90 The primary advantage of using SBS to fabricate these materials is increased production rate, which will make processes more cost-efficient and thus more accessible to researchers and markets.…”

Solution blow spinning (SBS) is a technique that can be used to deposit fibers in situ at low cost for a variety of applications, which include biomedical materials and flexible electronics. This review is intended to provide an overview of the basic principles and applications of SBS. We first describe a method for creating a spinnable polymer solution and stable polymer solution jet by manipulating parameters such as polymer concentration and gas pressure. This method is based on fundamental insights, theoretical models, and empirical studies. We then discuss the unique bundled morphology and mechanical properties of fiber mats produced by SBS, and how they compare with electrospun fiber mats. Applications of SBS in biomedical engineering are highlighted, showing enhanced cell infiltration and proliferation versus electrospun fiber scaffolds and in situ deposition of biodegradable polymers. We also discuss the impact of SBS in applications involving textiles and electronics, including ceramic fibers and conductive composite materials. Strategies for future research are presented that take advantage of direct and rapid polymer deposition via cost-effective methods.

“…It is worth noticing that SBS is superior to ES in terms of production efficiency due to its high solution feeding rate per orifice (2.0–10.0 g/h) [ 17 ]. It is reported that SBS can produce tens of times more nanofibers than ES with an improved cost/benefit ratio [ 18 ]. Additionally, apart from restriction on the electrical polymer solution and high-voltage equipment are not required, it is easy to use as a die assembly with many nozzles without considering of electric field interference [ 19 ].…”

Solution blow spinning (SBS) is an innovative process for spinning micro/nanofibers. In this paper, polyamic acid (PAA) nanofibers were fabricated via a SBS apparatus and then imidized into polyimide (PI) nanofibers via thermal process. The morphology and diameter distributions of PAA nanofibers were determined by scanning electron microscope (SEM) and Image Tool software, the processing parameters, including PAA concentration, solution feeding rate, gas pressure, nozzle size, and receiving distance were investigated in details. The fourier transform infrared spectroscopy (FTIR) was used to characterize the chemical changes in the nanofibers after thermal imidization. The results showed that the solution concentration exhibited a notable correlation with spinnability, and the formation of bead defects in PAA nanofibers. Solution feeding rate, gas pressure, nozzle size, and receiving distance affected nanofiber production efficiency and diameter distribution. The average diameters of fibers produced ranged from 129.6 to 197.7 nm by varying SBS parameters. Precisely, PAA nanofibers with good morphology were obtained and the average diameter of nanofibers was 178.2 nm with optimum process parameter. After thermal imidization, the PI nanofibers exhibited obvious adhesion morphology among interconnected fibers, with an increased average diameter of 209.1 nm. The tensile strength of resultant PI nanofiber mat was 12.95 MPa.

“…These materials could also be texturized, thereby increasing the superficial area between nearby grains; this improves electrical junctions and aligns superconductor planes [15][16][17][18][19][20][21]. Recently, BSCCO fibers were obtained by the electrospinning technique [10] by using a sol-gel precursor; these fibers had an average diameter of 150-250 nm with Tc of~78.7 K. Furthermore, our research group has synthesized YBaCu fibers by SBS [22].…”

This paper presents the synthesis and characterization of BSCCO superconducting fibers synthesized by heattreating poly(vinyl pyrrolidone) (PVP)/BSCCO precursor microfibers produced by the solution blow-spinning technique. Different concentrations (v/v) of the BSCCO precursor were added to the PVP solution to evaluate the influence of solution viscosity on fiber morphology. The production of PVP/BSCCO microfibers and their morphology were strongly influenced by the volatility of the solvent and the concentration of the added BSCCO in the solution. After heat-treatment, fibrous structures were obtained for the BSCCO system. The structural properties of the samples were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The XRD pattern revealed the formation of Bi 2 Sr 2 Ca 1 Cu 2 O x and Bi 1,9 Sr 1,8 CuO 5,5 phases. Finally, electrical measurements (R×T) showed electrical resistance decay at the transition temperature (Tc) that was typical of that observed in superconductor materials.
