“…Two electrospinning setups were used for assessing the scalability and throughput of the process. The first one was a conventional nozzle-based setup, and the second was a high-throughput nozzle-free system with a rotating collector mounted inside an isolated environmental chamber [23]. A heat gun was mounted externally to allow for chamber temperature control.…”

“…Increasing relative humidity is associated with decreasing fiber diameter, which in turn may result in materials with decreased mechanical properties such as ultimate tensile strength [42,43] The home-built nozzle-free setup had a rotating collector and a rotating drum partially immersed in a Teflon bath containing the polymer solution. Details of this setup can be found in our previous technical paper [23]. The experimental conditions were a potential difference of 60 kV, a working distance of 15 cm, and the relative humidity recorded was within the range of 5 to 7.5%.…”

Electrospinning has rapidly progressed over the past few decades as an easy and versatile way to fabricate fibers with diameters ranging from micrometers to tens of nanometers that present unique and intricate morphologies. This has led to the conception of new technologies and diverse methods that exploit the basic electrohydrodynamic phenomena of the electrospinning process, which has in turn led to the invention of novel apparatuses that have reshaped the field. Research on revamping conventional electrospinning has principally focused on achieving three key objectives: upscaling the process while retaining consistent morphological traits, developing 3D nanofibrous macrostructures, and formulating novel fiber configurations. This review introduces an extensive group of diverse electrospinning techniques and presents a comperative study based on the apparatus type and output. Then, each process's advantages and limitations are critically assessed to identify the bona fide practicability and relevance of each technological breakthrough. Finally, the outlook on future developments of advanced electrospinning technologies is outlined, with an emphasis on upscaling, translational research, sustainable manufacturing and prospective solutions to current shortcomings.

“…[ 86 ] Polymer solution is brushed on to a string and multiple jets are formed under high electrostatic field. In addition, bubble‐based electrospinning [ 87 ] and cylinder‐based electrospinning [ 88 ] are the other forms of nozzle‐less electrospinning. The creation of a thin solution membrane is crucial for nozzle‐less electrospinning.…”

Nanofiber‐based products are widely used in the fields of public health, air/water filtration, energy storage, etc. The demand for nonwoven products is rapidly increasing especially after COVID‐19 pandemic. Electrospinning is the most popular technology to produce nanofiber‐based products from various kinds of materials in bench and commercial scales. While centrifugal spinning and electro‐centrifugal spinning are considered to be the other two well‐known technologies to fabricate nanofibers. However, their developments are restricted mainly due to the unnormalized spinning devices and spinning principles. High solution concentration and high production efficiency are the two main strengths of centrifugal spinning, but beaded fibers can be formed easily due to air perturbation or device vibration. Electro‐centrifugal spinning is formed by introducing a high voltage electrostatic field into the centrifugal spinning system, which suppresses the formation of beaded fibers and results in producing elegant nanofibers. It is believed that electrospinning can be replaced by electro‐centrifugal spinning in some specific application areas. This article gives an overview on the existing devices and the crucial processing parameters of these nanofiber technologies, also constructive suggestions are proposed to facilitate the development of centrifugal and electro‐centrifugal spinning.
