Annotation:
Electrospinning is a process, during which, with electrostatic forces acting, nano- microfibres are produced from a polymer solution or a melt. Nano- microfibres have unique properties: large area of specific surface, porosity (high porosity level, small size of pores) and small diameter. Due to these properties, nano- microfibres and nano-microfibre- based materials are especially widely used in medicine, and in production of filters, protective clothes, composites, optical and electronic devices. On the basis of various research results provided in different literature sources, it has been noticed that quite often when analysing the impact of the same parameter on the web structure, the authors obtain different results. While analysing what causes contradictory research results obtained by different authors, a conclusion has been made that essentially this phenomenon is caused by the fact that no uniform methods for nano-microfibre web estimation have been created so far. As there are no common methods of estimation, it is difficult to compare the works by different authors. Therefore, the research in the nano-microfibre web field is extremely important and necessary not only in order to optimize electrospinning process, but also estimate properly the impact of different parameters on the diameter and structure of the web.
