Poster summary

The purpose of this poster paper is to study the dielectric charging of polymer fibers with the electron plasma charging effects accompanied by the emergence of waves propagating along the polymer fiber surface. Monitoring of the charge propagation along the single fiber has been performed using dielectric polyhydroxybutyrate fibers obtained by the electrospinning method under the electron beam inside the scanning electron microscope chamber. We also propose to introduce a novel method for isopotential mapping of electron beam-induced dielectric charging of the nonwoven fabric fibers using Sobel-Feldman gradient operator and dynamic electron microscopy setup with an electron beam. Images of the dynamic behavior of a double layer of polyxydroxybutyrate dielectric fiber under the electron beam charging at three levels of magnification are presented.
