ABSTRACT
Nanotechnology is considered one of the most promising technologies for the twenty-first century. Nanotechnology is used when either nanoscaled materials are produced (defined by their thickness, particle size, or other structural features) or the nature of a process involves the use of nanoscaled materials. Nanotechnology is considered the future in manufacturing technology that will result in products that are lighter, stronger, cleaner, less expensive, and more precise. Research and development in nanotechnology are directed toward understanding and creating improved materials, devices, and systems that exploit these new properties.[1]
Electrospinning, discovered in the early 1900s, as a branch of nanotechnology, has attracted a lot of interest as a novel technique that is a very simple and inexpensive way of manufacturing continuous nanofibers ranging from less than 10 nm to over 1 µm in diameter. The ability to electrospin fibers from diverse classes of material has resulted in a huge range of potential applications and growing interest in the process by researchers worldwide. It has potential application in filters, tissue engineering scaffolds, wound dressings, drug delivery materials, biomimetic materials, composite reinforcement, protective clothing, electronics, implants, agriculture, and many other areas.[2]
The electrospinning process (Figure 2) is based on a simple concept of creating nanofibers through an electrically charged jet of polymer solution or polymer melt, as shown in Figure 1.
