Electrospinning technology

In electrospinning technology, the control of fiber diameter is the key. The diameter of fibers formed during electrospinning is influenced by  

The formation of fibers in the electrospinning process is also influenced by surface tension derived from the applied electrical charge to the polymer. 

Recent experiments have demonstrated that the rapidly vyhipping fluid jet is an essential mechanism of electrospinning. ° i Different collection systems are knovyn. Typically, in producing nonwoven mats, metal plates are used in counter electrodes and in collection systems for the nanofibers or nano-vyebs. In some special apphcations, additional grounded collectors are necessary.

CNY is manufactured by means of electrospinning technology (Doshi and Reneker, 1995). The natural nanofibrils of bacterial cellulose are produced by several species of bacteria, for example, G. xylinus. The biosynthesized long and thin elementary nanofibrils of bacterial cellulose are aggregated to microfibrils forming a network filled with water. 

The CNY obtained by electrospinning technology is a porous nonwoven mat with a high absorption capacity. Due to its features this nanomaterial can be used for wound dressing, tissue scaffolds, drug delivery systems, etc. (Vargas, 2010). 

Aramid nanofibers have been prepared by an electrospinning technology [25]. The addition of LiCl plays an important role both for helping dissolving and in electrospinning because the electrical conductivity of the solution increases. These nanofibers can selectively absorb certain materials. For example, aramid nanofibers can be used to effectively remove endocrine dismptors such as bisphenol A, phenol, and p-hydroquinone from their aqueous solutions. Also, the nanofibers can be used in molecularly imprinted technology.

Each of these structures has led to different applications and together they have greatly expanded the scope of electrospinning technology in meeting the needs of the next generation of polymer-based products. ... 

Electrospinning technology has been shown to be a facile and versatile method to manufacture nanoscale fibrous membranes. Electrospun fiber membranes have gained much attention due to their properties such as smaller pore size, higher porosity, and air permeability, compared to the conventional nonwovens. Recently, organic (Chen et al. 2011), inorganic (Li and Xia 2003 Ding et al. 2004 Park and Lee 2010),... 

Nair and co-workers were also using electrospinning technology to form polyphosphazene fibres for TE purposes [4]. They found that the nature of the solvent, the diameter of the electrospinning needle, the solution concentration and the applied voltage had significant...
