“…The structure and mechanical characteristics of nanofiber mats produced by electrospinning rely on a number of factors, including the collector type [ 40 ], rotating drum speed [ 41 ], collector distance, syringe diameter, and polymeric solution flow rate via the syringe [ 42 ]. Reducing the nanofiber’s diameter enhances its strength [ 21 ].…”

Electrospun nanofibers are very popular in polymer nanocomposites because they have a high aspect ratio, a large surface area, and good mechanical properties, which gives them a broad range of uses. The application of nonwoven structures of electrospun nanofiber mats has historically been limited to enhancing the interlaminar responses of fiber-reinforced composites. However, the potential of oriented nanofibers to improve the characteristics of bulk matrices cannot be overstated. In this research, a multilayered laminate composite was created by introducing polyamide (PA6)-oriented nanofibers into an epoxy matrix in order to examine the effect of the nanofibers on the tensile and thermal characteristics of the nanocomposite. The specimens’ fracture surfaces were examined using scanning electron microscopy (SEM). Using differential scanning calorimetry (DSC) analysis, the thermal characteristics of the nanofiber-layered composites were investigated. The results demonstrated a 10.58% peak in the nanocomposites’ elastic modulus, which was compared to the numerical simulation and the analytical model. This work proposes a technique for the development of lightweight high-performance nanocomposites.

“…The average mean tensile strength of PAN nanofiber mat is 18.1 ± 2.9 MPa, and the average elongation is 2.6 ± 0.16 percent. PAN nanofiber mat offers 37.3% greater tensile strength and 50% less elongation than PA6 nanofiber mat [11]. Accordingly, the rigidity of PAN nanofiber mats is greater than that of PA6 nanofiber mats, giving PAN nanofiber mats enormous potential for usage in heavy composite structures and smart materials.…”

“…The morphology of the nanofiber mat generated in response to the speed of the rotating drum determines the mechanical characteristics of Polyacrylonitrile (PAN) nanofibers.

Nanofibers have acquired greater interest due to their vast variety of possible uses. Nanofibers offer several options to change things physically and chemically during or after the manufacturing process to give them new properties. To exploit the full potential of nanofibers, it is necessary to comprehend the link between the mechanical characteristics, particularly tensile strength, of a nanofiber mat and its morphology. Electrospinning is a rapidly developing polymer processing technology because it provides a simple and effective method for manufacturing nano continuous fibres. This method permits the deposition of nanofibers on revolving collectors. Rotating collectors, such as the drum and electrodes with a gap between them, may readily form oriented fibres. Polyacrylonitrile is a common precursor material for carbon nanofibers (PAN). This research investigates the impact of collector drum’s rotation speed on the morphology of the nanofiber mat and discusses the mechanical properties of Polyacrylonitrile (PAN) electro spun nanofiber mats with precisely aligned nanofibers. PAN nanofiber mats have more tensile strength (~37 %) than PA6 nanofiber mats and have (50 %) less elongation than PA6 nanofiber mats, according to a comparison with previous studies.

In recent years, as microelectronics technology advances, the number of miniature devices has increased as well as the demand for power supply. Polymer-based electrospun nanofiber membranes have been used as lithium-ion (LI) battery separators and filtration medium. This study investigates the mechanical properties of orientated polyamide 6 (PA6) and polyacrylonitrile (PAN) nanofiber mats prepared by electrospinning a solution containing PAN and PA6, separately. The PA6 granules and the PAN powder were dissolved in formic acid solvent and N, N-dimethylformamide solvent, respectively. To generate the composite mat, the PA6 nanofiber mat was first electrospun, followed by the PAN nanofiber mat directly electrospun on the PA6 nanofiber mat. In our experiment, we employed the following electrospinning parameters: a voltage of 25 kV, a flow rate of 0.65 ml/h, 25 cm between the tip of the syringe and the drum collector centre, and a constant rotating speed of 1800 rpm. The mechanical properties of nanofiber composite mats, such as the tensile strength and Young’s modulus, were examined. The results demonstrate a reduction in the tensile strength and an increase in the elastic modulus of the composite nanofiber mats by 12% and 126% compared to PA6 nanofiber mats, respectively. The structure of spun nanofibers enables their use as separators for lithium-ion batteries and as a filtering medium. This article suggests the improved mechanical characteristics of nanofiber membranes for use as a barrier in lithium-ion batteries and for filtration.
