Blowspinning: A New Choice for Nanofibers

Abstract

Blowspinning is a new technique that enables the large-scale production of fibers with diameters ranging from micrometer to nanometer, which is more like a combination of melt-blown and electrospinning but has its own characteristics. This method can be used to deposit fibers in situ and produce various fibrous materials, such as coating, nonwoven, and sponge. These characteristics provide a new strategy for nanofiber application and attract the interest of many researchers. Regarding the blowspinning technique, systematic research had been carried out, involving basic principles, empirical studies, spinning equipment, and application. This review is intended to emphasize trends and gaps in the form of a concise illustration of various research directions.

Tailoring the Surface Properties of Micro/Nanofibers Using 0D, 1D, 2D, and 3D Nanostructures: A Review on Post‐Modification Methods

“…Solution blow spinning (SBS) [ 56,76,77 ] involves the use of pressurized gas that acts as a driving force as well as promotes solvent evaporation to form fibers from a polymer solution continuously extruded through a nozzle, as illustrated in Figure 1b. [ 9 ] SBS and their variations are also called air spinning or air‐jet spinning, [ 78,79 ] solution blowing, [ 80,81 ] gas jet spinning, [ 82 ] airbrushing, [ 83 ] and pressure‐driven spinning.…”

“…[ 84 ] During the SBS process, the gas pressure is converted into kinetic energy and generates a shearing force that results in the deformation of the droplet of polymer solution at the tip of the nozzle, leading to the formation of a cone‐like shape. [ 76 ] When the shearing force overcomes the solution surface tension force, a polymer jet is ejected from the tip of the cone, which is then moved toward the target. During this trajectory, the polymer jet elongates, reducing its diameter, and the solvent evaporates, which results in the formation of a fiber network that can be deposited onto practically any surface.…”

“…During this trajectory, the polymer jet elongates, reducing its diameter, and the solvent evaporates, which results in the formation of a fiber network that can be deposited onto practically any surface. [ 76 ] Similarly to electrospinning, the diameter and morphology of SBS spun fibers are dependent on several parameters classified into three main categories: solution parameters (concentration, viscosity, solvent volatility, and surface tension), processing parameters (gas pressure, nozzle structure, the flow rate of the liquid, and the distance between the tip of the nozzle and the collector), and environment parameters (temperature and humidity). [ 56,78–81,85 ] Compared with electrospinning, SBS offers advantages including i) low cost and use of a simple apparatus; ii) no need of a high voltage power supply; iii) the preparation of fibers from materials with low dielectric constant and/or electrical conductivity; iv) allows portability as well as fiber deposition onto any surface, and v) high productivity and easy scale‐up.…”

Preparation of Perfluorosulfonated Ionomer Nanofibers by Solution Blow Spinning

“…We think that blowspinning is the most promising for high-throughput production of relatively thin ion-exchange NFs. Solution blow spinning (SBS) was proposed by Mederiou et al in 2009 [20] and has been developed rapidly in the past decade [21,22]. This process is based on the high-speed stretching of airflow and the Bernoulli principle, by which the change in air pressure is converted into the kinetic energy of the solution.…”

Complexos de nanofibras eletrofiadas e ácidos nucleicos: Uma revisão

“…Sua produção faz uso de técnicas aplicadas em larga escala como a fiação conjugada (Pike, 1999), fibrilação de película fundida (Perez et al, 2000) e a fiação por sopro em solução (Perez et al, 2000). Atendendo a diversas especificidades de síntese e as propriedades do material (viscoelasticidade, condutividade, temperatura de transição vítrea e de degradação térmica) em associação às características desejadas para as fibras (diâmetro, comprimento, conformação sólida ou tubular, alinhamento e regularidade das fibras), outras técnicas também são utilizadas: automontagem (Sun et al, 2017), molde estrutural (Tao & Desai, 2007), separação de fases (J. F. Kim et al, 2016;, polimerização interfacial (El-Basaty et al, 2020), fiação por sopro em solução (Song et al, 2020) e a eletrofiação.…”
