Analysis of the influence of the rate of electrospinning on the structure and properties of nanofibrous web

The object of research is electrospun nanofibrous webs. The aim of this work is to determine the effect of the collector rotation frequency on the fibers arrangement in the electrospun webs, as well as to assess the effect of fibers orientation on their deformation properties. It is proved that an increase in the frequency of rotation of the collector of the Fluidnatek LE-50 installation from 200 to 2000 min-1 leads to an increase in the degree of orientation of the nanofibers without a significant change in their average diameter. In this case, the distribution law of the angle of the fibers inclination changes from uniform to exponential one. With an increase in the degree of fibers orientation the strength of the electrospun web increases significantly and their breaking elongation decreases.
