Self-Induced Localized Electric-Field-Enhanced Electrostatic Electron Emission in Polypropylene Surface-Based Roll-to-Roll Manufacturing

The roll-to-roll (RtR) Manufacturing can produce a large amount of electrostatic charges. In terms of industrial safety, a large amount of energy can be released via electrostatic discharge (ESD) that can cause severe shocks, which can be a risk to automated machines, operators, and merchandise. In...
