Traps energy distribution in Kapton HN polyimide films through surface potential decay model under humidity conditions

High energy density of polyimide films employing an imidization reaction kinetics strategy at elevated temperature

“…7b shows that the ODPA-MPD-3 lm with an The bipolar carrier transport model was used to reveal the inuence of trap characteristics on the process of charge transport. [49][50][51] Electrons and holes were injected into the ODPA-MPD lms at 50 MV m À1 by electrodes on the lm surface. Under the action of an electric eld, the charges migrated, diffused, and accumulated in the area near the electrodes.…”

High-temperature energy storage performances of “isomer-like” polyimide and its thermoplastic polyurethane blending system

“…The bipolar carrier transport model intuitively describes the charge transport mechanism inside the i-PI and TPU/i-PI films. [37][38][39][40][41] Sources of electrons and holes in the films are injected from the electrodes at 50 MV m À1 . The charges injected by the electrodes migrate and accumulate within the i-PI and TPU/i-PI films when an electric field is applied.…”

Surface electric charge decay behavior of Polypropylene (PP) films treated by atmospheric air dielectric barrier discharge

“…Most studies have been focused on adhesion, surface morphology, chemical composition, and wettability, but only few works concerning surface electrical properties, particularly the effect of dielectric barrier geometrical parameters on surface charge properties have been reported. Surface potential decay (SPD) measurement using a non-contact electrostatic voltmeter has been proved to be the most practical method to study the evolution of the amount of charge deposited on polymeric materials after subjection to the corona discharge [11][12][13]. This method has been used by many researchers to study the fundamental phenomena related to the electrical charging and discharging processes at the surface of insulating materials [11][12][13].…”

This method has been used by many researchers to study the fundamental phenomena related to the electrical charging and discharging processes at the surface of insulating materials [11][12][13]. This work aims to evaluate the effect of DBD treatment on the evolution of SPD of polypropylene (PP) films after negative corona charging.…”
