Introduction

The fabrication of polymer nanofibers through electrospinning has emerged as a versatile and powerful technique for developing advanced materials with tailored properties for a wide array of applications. This methodology allows for the production of continuous fibers with diameters ranging from nanometers to micrometers, offering a high surface area-to-volume ratio and tunable porosity. The field has witnessed significant growth, with researchers exploring diverse polymer systems and their potential in fields such as filtration, biomedicine, and energy storage. Polyacrylonitrile (PAN) nanofibers have demonstrated considerable promise in air filtration due to their exceptional surface area, which is crucial for efficient particulate matter capture. The electrospinning process parameters, including solution concentration, voltage, and tip-to-collector distance, can be manipulated to control the morphology of the resulting nanofibers, leading to enhanced performance in conventional filter media alternatives [1].

Cellulose acetate nanofibers, another important class of electrospun materials, are being investigated for advanced wound dressing applications. Their biocompatibility and biodegradability, coupled with the ability to control fiber diameter and porosity through solvent system selection, make them ideal for promoting wound healing by maintaining a moist environment and facilitating cell proliferation [2].

Functionalized nanofibers are also gaining traction. For instance, polyvinyl alcohol (PVA) nanofibers loaded with silver nanoparticles (AgNPs) have been developed for antimicrobial textiles. The co-electrospinning technique ensures uniform dispersion of AgNPs within the PVA matrix, resulting in nanofibers with significant antibacterial activity against common pathogens, thus offering hygienic fabric solutions for healthcare and sportswear [3].

In the realm of tissue engineering, chitosan nanofibers are proving to be valuable scaffolds. The electrospinning process allows for optimization of their mechanical properties and pore structure, making them suitable for promoting cell adhesion and proliferation. Their inherent biocompatibility and bioactivity suggest significant potential for applications in bone and cartilage regeneration [4].

For environmental remediation, electrospun nylon-6 nanofibers are being utilized as membranes for oil-water separation. The hydrophobic nature of nylon-6, combined with the porous nanofiber structure, provides excellent water repellency and oil permeability, offering an effective solution for tackling oil spill pollution [5].

Polylactic acid (PLA) nanofibers fabricated via electrospinning are being explored for sophisticated drug delivery systems. The ability to control porosity and high surface area allows for precise modulation of drug encapsulation efficiency and in-vitro release kinetics, paving the way for personalized medicine applications [6].

In cardiovascular tissue engineering, a blend of polyurethane (PU) and gelatin has been electrospun to create nanofibers with enhanced mechanical strength and biocompatibility. These composite scaffolds show promise in promoting vascular regeneration due to the synergistic properties of the constituent polymers [7].

Nerve regeneration is another area benefiting from electrospun nanofibers. Poly(ethylene oxide)-poly(caprolactone) (PEO-PCL) nanofibers have been fabricated, with processing parameters optimized to influence fiber diameter and mechanical properties. These nanofibers can serve as guidance conduits, facilitating nerve repair [8].

Finally, cellulose nanofibers produced by electrospinning are finding applications in energy storage, particularly as separators in lithium-ion batteries. Their high porosity and thermal stability contribute to improved battery performance and safety, representing a sustainable approach for advanced battery component development [9].
