Overview of Nano-Fiber Mats Fabrication via Electrospinning and Morphology Analysis

Abstract

Electrospun nano-fibers exhibit two significant properties: a high surface-to-volume ratio and a relatively defect-free molecular structure. Due to the high surface-to-volume ratio, electro-spun materials are well suited for activities requiring increased physical contact, such as providing a site for a chemical reaction or filtration of small-sized physical materials. However, electrospinning has many shortcomings, including difficulties in producing inorganic nanofibers and a limited number or variety of polymers used in the process. The fabrication of nanofiber bundles via electrospinning is explored in this analytical study and the relationship between all effective electrospinning parameters and the relative abundance of various fiber morphologies. Numerous variables could impact the fabrication of nanofibers, resulting in a variety of morphologies such as uniform, entangled, individual beads, beads-on-string, etc. Therefore, adequate ambient conditions and selecting the appropriate polymer and solvent for achieving a homogenous polymer solution and uniform with desired nanofiber properties for different applications of electro-spun materials are examined. Finally, the promising applications of nano-fine fibers in various fields achieved via electrospinning are studied in this paper.

Advancing bone tissue engineering one layer at a time: a layer-by-layer assembly approach to 3D bone scaffold materials

“…It is well proven that microscale structures ensure the primary attachment in the bio-interface of the scaffolds and promote cell interaction while nanoscale organization has more significant effects on the adhesion and differentiation of cells. [194][195][196] Bone consists of a mineral phase in the form of apatite nanocrystals embedded in a collagen matrix. 197 The nanometre-sized HA crystals play a key role in the high mechanical properties exhibited by bone.…”

Electrospinning Synthesis of Na0.5Bi0.5TiO3 Nanofibers for Dielectric Capacitors in Energy Storage Application

“…The electrospinning process is affected by a variety of parameters, such as ambient parameters, solution parameters, and processing parameters. Ambient parameters mainly include temperature and humidity, solution parameters mainly include solution concentration, viscosity, conductivity, and surface tension, and the processing parameters on electrospinning mainly include applied voltage, solution flow rate, and collector’s rotation speed [ 29 , 36 , 37 , 38 ]. Indeed, electrospinning technology was previously used in preparing ceramic nanofibers for energy storage applications [ 39 ].…”

A Microvascular System Self-Healing Approach on Polymeric Composite Materials

“…Comparing the three known encapsulation methods, the development of nano-fibres through the electrospinning process is shown to be more cost-efficient solution to cover a larger, multiple healing area due to its random entanglement of nanofibers. Another major advantage of the electrospinning process relies in the controllability of the process to obtain a higher surface-area-to-volume ratio and the formation of a homogenous structure with no defects [ 15 ].…”
