what is the "Nanofiber"

Nanofiber = Nanosize(10^-9 m) fiber.

Nanofiber has diameters ranging from several micrometers to tens of nanometers.

And it is fibrous material that its length is 100 times greater than the diameter.

Nanofiber membranes has a large surface area per unit mass and a very small pore size.

These characteristics make the nanofibers have many potential applications

such as optical materials, sensor materials, nanocomposite materials, tissue scaffolds,

wound dressing, drug delivery systems, filtration, and as protective clothing .

[How to produce the Nanofiber]

Nanofiber is prepared by several method

(Electrospininng, Melt blown, Melt spinning, and so on).

In these method, Electrospinning is becoming of great interest

because not only it can produce polymer fibers

with diameters in the range of nano- to a few micrometers,

but it also has the advantages of being simple, convenient,

and inexpensive as compared with conventional methods.

At the present, almost nanofibers fabricated via electrospinning.
