“…Nanofibers are produced in various ways such as wet-spinning [ 2 ], dry-spinning or melt spinning [ 3 , 4 ], template synthesis [ 5 ], solution blow spinning [ 6 ], and force spinning [ 7 ], but the most common and highly effective way is through an electrospinning (electrostatic spinning) technique, i.e., the fabrication of nanofibers using electrostatic forces [ 8 ]. Electrospun nanoscale fibers are mainly fabricated from polymer solution or polymer melts [ 9 ]. Though electrospinning has advanced rapidly in the past three decades, the technique itself and the fabrication parameters still need to be enhanced and improved to match commercial requirements.…”

“…Though electrospinning has advanced rapidly in the past three decades, the technique itself and the fabrication parameters still need to be enhanced and improved to match commercial requirements. For example, obtaining clog-free electrospun nanofibers is still a challenge [ 9 ]. However, with technological advancements and extensive research, electrospinning technology has evolved from lab-made nanofibers to more advanced products.…”

“…However, with technological advancements and extensive research, electrospinning technology has evolved from lab-made nanofibers to more advanced products. Extensive research has led to the fabrication of nanofibers with increased strength, more controllable morphology (length, orientation, porosity, diameter, shape, size, and alignment), and new functionalities [ 9 ]. One aspect for improvement would be the physicochemical characteristics of the nanofibers by appropriately selecting basic materials to enhance porosity and durability.…”

Nanofibers are one of the most attractive materials in various applications due to their unique properties and promising characteristics for the next generation of materials in the fields of energy, environment, and health. Among the many fabrication methods, electrospinning is one of the most efficient technologies which has brought about remarkable progress in the fabrication of nanofibers with high surface area, high aspect ratio, and porosity features. However, neat nanofibers generally have low mechanical strength, thermal instability, and limited functionalities. Therefore, composite and modified structures of electrospun nanofibers have been developed to improve the advantages of nanofibers and overcome their drawbacks. The combination of electrospinning technology and high-quality nanomaterials via materials science advances as well as new modification techniques have led to the fabrication of composite and modified nanofibers with desired properties for different applications. In this review, we present the recent progress on the fabrication and applications of electrospun nanofiber composites to sketch a progress line for advancements in various categories. Firstly, the different methods for fabrication of composite and modified nanofibers have been investigated. Then, the current innovations of composite nanofibers in environmental, healthcare, and energy fields have been described, and the improvements in each field are explained in detail. The continued growth of composite and modified nanofiber technology reveals its versatile properties that offer alternatives for many of current industrial and domestic issues and applications.

Fibrous biomaterials have received much attention in tissue engineering and regenerative medicine due to their morphology, resembling extracellular matrix. In comparison to synthetic fibers, cellulose based fibers have interesting properties for cellular applications such as biodegradability, biocompatibility, simple preparation and their potential for chemical modification. Among cellulose derivatives, carboxymethyl cellulose and quaternized cellulose are the most important and valuable cellulose ethers which have anionic and cationic surface charge. In this research, we report the fabrication of multifunctional cellulose microfibrous and nanofibrous scaffolds and the comparison of adhesion and spreading potential of human fibroblast cell on them. The fabricated fibrous scaffolds were characterized by several instrumental techniques. The results showed that multifunctional cellulose nanofibers and microfiber had 8.6 and 8.2 mV surface potential, 7.1 and 6.8 MPa tensile strength, 560 and 510 MPa Young modules, 610 and 595% water uptake and 41o and 44o contact angle, respectively. The MTT assay showed that proliferation of fibroblast cells was enhanced in nanofibrous, compared to microfibrous mat. The SEM analysis of fixed cells on scaffolds showed that cells spreading on nanofibrous samples became more noticeable than microfibrous ones.

“…The commercial membranes like nanofiltration and conventional membranes are porous in nature and typically produced via phase immersion method, where it is very difficult to achieve the uniform porosity which resulted in the lower water flux [8][9][10]. With the development of the electrospinning technique, most of the synthetic polymer nanofibers have been applied extensively into diverse research fields and industries like air purification, gas storage , drug delivery, sensors, tissue engineering and electrodes for use in electronics [11][12][13][14][15][16]. During the electrospinning process, when the applied voltage is strong enough to overcome the surface tension of the (charged) polymer solution at the tip of the spinneret, a fine jet stream is ejected.…”
