A new variant of the Laser-Induced Pressure-Pulse (LIPP) method for repeatable, time-resolved space-charge profile measurements is proposed and demonstrated. Automated deposition of a fresh laser-target film before each illumination leads to good repeatability of the LIPP and thus allows for the detection of time-resolved changes in the space ... Web15. dec 2024 · It is obvious that in this study, with a high GR content, the dielectric loss of GR/PVDF composites is mainly originated from DC conduction. As the space charges have a low response frequency, the dielectric loss decreases with the increasing frequency at 100 Hz - 1 MHz, which is consistent with the previous report [ 16 ].
