Isopotential Mapping of Electron Beam Induced Dielectric Charging of the PHB Nonwoven Fabric Structures Using Sobel-Feldman Gradient Operator

The aim of this brief methodological report is 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 for the first time in this report.
