“…There are three typical electrospinning setups [ 27 , 28 , 29 , 30 , 31 ]—horizontal, top-down, and bottom-up. In the horizontal system, the needle tip and collector are arranged in such a way that electrospinning happens parallel to the ground.…”

Electrospinning is a versatile fibre fabrication method with applications from textile to tissue engineering. Despite the appearance that the influencing parameters of electrospinning are fully understood, the effect of setup orientation has not been thoroughly investigated. With current burgeoning interest in modified and specialised electrospinning apparatus, it is timely to review the impact of this seldom-considered parameter. Apparatus configuration plays a major role in the morphology of the final product. The primary difference between spinning setups is the degree to which the electrical force and gravitational force contribute. Since gravity is much lower in magnitude when compared with the electrostatic force, it is thought to have no significant effect on the spinning process. But the shape of the Taylor cone, jet trajectory, fibre diameter, fibre diameter distribution, and overall spinning efficiency are all influenced by it. In this review paper, we discuss all these developments and more. Furthermore, because many research groups build their own electrospinning apparatus, it would be prudent to consider this aspect as particular orientations are more suitable for certain applications.

“…By controlling the flow rates of the two different solutions, a core shell droplet is formed at the tip of the coaxial needle which has a shape similar to the Taylor cone as a result of the pulling action of the electric Maxwell. 8 Magnetic resonance imaging (MRI) is one of the most powerful noninvasive imaging techniques that offers visualization of anatomical structures with both high spatial resolution and unlimited tissue penetration depth. 9 MRI enables early diagnosis of many diseases including cancer, cardiovascular dysfunction, and problems related to the brain and central nervous system.…”

“…[1,2] These important properties make the polymer nanofibers as the most suitable candidate for many important applications such as tissue engineering, filtration, drug delivery, solar systems, and wound dressing applications. [3,4] In recent years, polymer nanofibers can be obtained with several processing techniques such as drawing, [5] template synthesis, [6] phase separation, [7] self-assembly, [8] and electrospinning. [9,10] Among these various methods, electrospinning is a technology in which electric forces are used to obtain polymer fibers with diameters changing from 2 nm to a small number of micrometers using polymer solutions or melt of both synthetic and natural polymers.…”

“…[10,11] Moreover, this technique has the advantage of being economically convenient, fast, and simple process to apply. [4,10,12] However, the low productivity is conceived as the principal disadvantage of this technique.

“…[4,10,12] However, the low productivity is conceived as the principal disadvantage of this technique. [4] In electrospinning method, a high voltage is applied to solutions of polymers between a syringe needle and a collector plate. When the induced charges in the polymer solution reach a critical value, the applied electrostatic forces cope with the surface tension of the polymer solution and then, the drop of cone in the tip of the needle comes to a cone shape which is called Taylor cone and the liquid jet begins to spray from the cone.…”

Nanofiber production was investigated from poly(ethylene terephthalate) (PET) polymers functionalized with hydroxyethyl methacrylate (HEMA) by grafting of HEMA monomers onto the PET fibers. HEMA grafted PET (PET‐g‐HEMA) copolymers were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy. PET and PET‐g‐HEMA were dissolved in trifluoroacetic acid and nanofibers were obtained by electrospinning. It was found that the PET and PET‐g‐HEMA polymers having grafting yield 20 and 55% could be converted to continuous, smooth, and beadles nanofibers. For characterization of the nanofiber membranes, thermogravimetric analysis, differential scanning calorimeter analysis, surface contact angle measurement, porosity analysis, and mechanical tests were applied. When compared with the original PET nanofibers, the thermal properties and degradation process of PET‐g‐HEMA nanofibers changed according to the amount of HEMA present in the structure of nanofibers. The contact angles of the nanofibers obtained from PET‐g‐HEMA polymers decreased whereas the water retention ability of the nanofibers increased compared to original PET nanofibers. The porosity of PET‐g‐HEMA nanofibers was found be high compared to PET nanofibers and whereas the mechanical properties of PET was higher than PET‐g‐HEMA nanofibers. The obtained nanofibers can be used in many fields such as biomaterial applications.
