Electrospinning is a simple, low-cost and versatile method for fabricating submicron and nano size fibers. Due to their large surface area, high aspect ratio and porous structure, electrospun nanofibers can be employed in wide range of applications. Biomedical, environmental, protective clothing and sensors are just few. The latter has attracted a great deal of attention, because for biosensor application, nanofibers have several advantages over traditional sensors, including a high surface-to-volume ratio and ease of functionalization. This review provides a short overview of several electrospun nanofibers applications, with an emphasis on biosensor applications. With respect to this area, focus is placed on label-free sensors, pertaining to both recent advances and fundamental research. Here, label-free sensor properties of sensitivity, selectivity, and detection are critically evaluated. Current challenges in this area and prospective future work is also discussed.

“…When the electric field overcomes the surface tension of the polymer solution, a charged jet ejects from the tip of needle, undergoes unstable whipping and bending motions between the tip of the needle and the collector, where the solvent evaporates and polymer in the nanofiber form is collected on the collector 26 – 28 . Electrospun nanofibers have attracted great attention due to their ease of fabrication, unique properties such as high surface-area-to-volume ratio, low density, and high pore volume and possibilities of functionalization 29 – 31 and used in a wide range of applications such as filtration 32 , energy harvesting and storage 33 , tissue engineering 34 , drug delivery 35 , wound healing 36 , sensors 37 , and polymer reinforcement 38 , etc. Composite nanofibers produced with the addition of different types of additives displayed additional functionalities.…”

Nanofibers with thermal management ability are attracting great attention in both academia and industry due to the increasing interest in energy storage applications, thermal insulation, and thermal comfort. While electrospinning is basically a fiber formation technique, which uses electrostatic forces to draw ultrafine fibers from a wide variety of polymers, with the addition of phase change materials (PCMs) to the electrospinning solution it enables the production of shape stabilized phase change materials with thermal management functionality. In this study, polyacrylonitrile (PAN) nanofibers containing paraffinic PCMs were produced by electrospinning method and the composite nanofibers obtained were characterized in terms of their morphology, chemical structure, thermal properties, stability, thermal degradation behaviour and hydrophobicity. Besides, PCMs with different phase transition temperatures were added simultaneously into the nanofiber structure in order to investigate the tunability of the thermoregulation properties of the nanofibers. Uniform nanofibers with thermal management functionality were obtained. It could be possible to obtain composite nanofibers showing thermoregulation ability over a wider temperature range by simultaneous addition of PCMs with different melting points into the nanofiber structure. 50 wt% PCM could be added to PAN nanofiber structure wherein the resulting nanofiber exhibited 58.74 J g−1 of enthalpy storage during heating and 57.41 J g−1 of heat release during cooling. The composite nanofibers maintained their cylindrical fiber morphology, structure and composition after multiple heating–cooling cycles and retained their thermal management functionality. The contact angle measurements showed that the addition of PCMs imparted hydrophobicity to the nanofibers.

“…However, since the late 1990s until now, the consciousness in this technique has been growing, as evident from the increasing number of publications, due to its ability to form webs with unique properties (eg, high specific surface area, small fibers' diameter, flexibility, ease of functionality, excellent mechanical properties, good pore structures, extraordinary adjustability, low density, and so on). Therefore, it can be used in various areas such as tissue engineering, biomedical applications, sensors, antibacterial applications, catalysts, energy harvesting, self‐cleaning surfaces, food packaging, filtrations, and so on.…”

Structures modification of fibers has been attracting significant attention in various fields and applications. Among different techniques of fabricating ultrathin fibers, electrospinning is the most commonly adopted method because of the ease of forming fibers with a wide range of properties and its exceptional advantages, such as the ability to spin into different shapes and sizes, as well as the adaptable porosity of electrospun fiber webs. The crimped structure has been attracting the attention of scientific researchers owing to its unique properties (eg, spring-like behavior, supreme strain, remarkable specific surface area, good piezoelectric properties, excellent biological properties, and so on). Therefore, this study summarizes a review of the strategies and methods, reported so far, of generating electrospun crimped ultrathin fibers of various polymers. The review focuses on the polymer types, formation methods, characterizations, and applications of the electrospun crimped ultrathin fibers. We believe this work can serve as an important reference for the materials, strategies, and applications of crimped fibers.
