1A2_0103_ NANOFIBROUS WEBS POROSITY AND THEIR STRUCTURE ESTIMATION

Abstract

The investigations in electrospinning process development have become very intensive in the last decades and a lot of papers have been published about the development of technology of electrospinning, influence of some parameters on electrospinning, possibilities to electrospun nanofibrous web from various polymers as well from the blends and with additional functional nano or micro particles. There is no single opinion about the reasons for such phenomena as the distribution of the nanofibre diameter is also very sophisticated. The main problem is that the measurements of the diameter are distributed in an unclear distribution, and to characterise webs mathematically and evaluate the shape of the distribution obtained is not easy.
