“…The results showed the MPEM could decrease the nanofiber diameter, enhance the diameter distribution, and improve the nanofiber alignment. Recently, using the ES technique, many functional nanomaterials have been developed using various polymers, such as poly(vinylidene fluoride) (PVDF) [25], poly(methyl methacrylate) (PMMA) [26,27], polylactic acid (PLA) [28], and poly-N-vinylpyrrolidone (PVP) [29,30]. Polyacrylonitrile (PAN), a well-known polymer with good stability and mechanical properties, has been widely used in producing electrospun nanofibers due to their excellent characteristics, such as spinnability, environmentally benign nature, and commercial availability [31].…”

Abstract:In the electrospinning process, a modified parallel electrode method (MPEM), conducted by placing a positively charged ring between the needle and the parallel electrode collector, was used to fabricate highly aligned carbon nanotubes/polyacrylonitrile (CNTs/PAN) composite nanofibers. Characterizations of the samples-such as morphology, the degree of alignment, and mechanical and conductive properties-were investigated by a combination of scanning electron microscopy (SEM), transmission electron microscopy (TEM), universal testing machine, high-resistance meter, and other methods. The results showed the MPEM could improve the alignment and uniformity of electrospun CNTs/PAN composite nanofibers, and enhance their mechanical and conductive properties. This meant the successful preparation of highly aligned CNT-reinforced PAN nanofibers with enhanced physical properties, suggesting their potential application in appliances and communication areas.

“…Gravitational forces act on the jet during electrospinning, accelerating the jet elongation and jet decay. Several studies exist to show the role of parameters and equations modeling the electrospinning process, generally considering gravitational forces to be constant throughout the process [39][40][41][42].…”

Electrospinning and polymer blending have been the focus of research and the industry for their versatility, scalability, and potential applications across many different fields. In tissue engineering, nanofiber scaffolds composed of natural fibers, synthetic fibers, or a mixture of both have been reported. This review reports recent advances in polymer blended scaffolds for tissue engineering and the fabrication of functional scaffolds by electrospinning. A brief theory of electrospinning and the general setup as well as modifications used are presented. Polymer blends, including blends with natural polymers, synthetic polymers, mixture of natural and synthetic polymers, and nanofiller systems, are discussed in detail and reviewed.

“…There are many factors affecting the morphology and property of nanofibers obtained in the MBE process, including properties of spinning solution (such as solution mass fraction, viscosity and electrical conductivity), spinning parameters (such as voltage, drum rotation speed and working distance), and environmental parameters (such as temperature and humidity) [12][13][14][15]. According to our previous work [5,8,16], the electrospinning parameters were set as follows.…”

Sodium dodecyl benzene sulfonates were used as a surfactant to obtain polyacrylonitrile nanofibers by a modified bubble-electrospinning using a copper coneshaped air nozzle. The properties of the electrospun solutions were investigated using viscosity meter, conductivity meter and rheometer, and the effects of sodium dodecyl benzene sulfonates concentration on the morphology, mechanical property and production of polyacrylonitrile nanofibers were studied. The results showed the addition of sodium dodecyl benzene sulfonates could effectively decrease the viscosity of the solution, increase the electric conductivity of the solution, and promote the generation of bubbles, which resulted in enhancing tensile strength and decreasing the production of nanofibers.
