“…The viscosity and concentration of the solution play an important role in the morphology and performance of the fiber [ 24 ]. Voltage and receiving distance directly affect the thickness of the fiber [ 25 ]. The humidity and temperature of the air affect the volatilization of the solvent during the jet flight, which ultimately affects the formation of the fibers [ 26 ].…”

In recent years, many different biosensors are being used to monitor physical health. Electrospun nanofiber materials have the advantages of high specific surface area, large porosity and simple operation. These properties play a vital role in biosensors. However, the mechanical properties of electrospun nanofibers are poor relative to other techniques of nanofiber production. At the same time, the organic solvents used in electrospinning are generally toxic and expensive. Meanwhile, the excellent performance of electrospun nanofibers brings about higher levels of sensitivity and detection range of biosensors. This paper summarizes the principle and application of electrospinning technology in biosensors and its comparison with other technologies.

“…When the electrostatic force overcomes the surface tension, it stretches the jet stream causing it to elongate as a filament. This filament solidifies and is eventually deposited on a grounded collector, these ultrafine fibers will form, and this process is then called electrospinning [ 24 ].…”

In the last two decades, several processes have been explored for the development of micro and/or nanostructured substrates by sagely physically and/or chemically manipulating polymer materials. These processes have to be designed to overcome some of the limitations of the traditional ones in terms of feasibility, reproducibility, and sustainability. Herein, the primary aim of this work is to focus on the enormous potential of using a high voltage electric field to manipulate polymers from synthetic and/or natural sources for the fabrication of different devices based on elementary units, i.e., fibers or particles, with different characteristic sizes—from micro to nanoscale. Firstly, basic principles and working mechanisms will be introduced in order to correlate the effect of selected process parameters (i.e., an applied voltage) on the dimensional features of the structures. Secondly, a comprehensive overview of the recent trends and potential uses of these processes will be proposed for different biomedical and bio-sustainable application areas.

“…Electrospinning can fabricate fine polymer fibers with diameters from tens to hundreds of nanometers through the application of a static electric field. [ 186 ] The morphology of electro‐spun nanofibers can be controlled by a variety of processing parameters, including voltage, [ 186–188 ] flow rate, [ 189,190 ] target distance, [ 191–193 ] solution viscosity, [ 194–197 ] and environmental humidity. [ 198–201 ] Building on the advantage of electrospinning which can improve the mechanical property through creating nanofibers with high aspect ratio, [ 202,203 ] aligning fillers within the fibers can further enhance composite performance to meet the requirement of many advanced applications.…”

Polymer composites are ubiquitous and indispensable in numerous applications. Coupling the inclusion of reinforcing agents with methods developed to control filler distribution and orientation allow for significant enhancement in mechanical, thermal, electrical, and barrier/transport‐related properties of composites. For practical implementation, ideal approaches to fabricating polymer composites with directionally assembled fillers must consider manufacturing compatibility, scale‐up ease, and aligning efficiency. In this article, we will review a cost‐effective and industrially relevant toolbox for preferential filler alignment in polymer composites. Three main strategies for aligning fillers within polymer composites will be discussed. Specifically, solution casting and compression molding can introduce compression force to assemble fillers along the in‐plane direction of composite films, shear force can be developed during fiber spinning, film blowing, and uniaxial/biaxial stretching processes to align fillers along the shear direction, and external fields (both electric and magnetic fields) can direct assembly of fillers, typically along the out‐of‐plane direction. For each section, we not only highlight the mechanisms of these methods but also demonstrate the critical structure–property relationships through model examples. Finally, a perspective on future opportunities and challenges of anisotropic and performance‐enhanced polymer composite preparation strategies is provided, with a particular focus on additive manufacturing.
