“…6,8 Dielectric materials charging by charged particles was also identified to be the cause of electrostatic discharges (ESD) and anomalous operations on the spacecraft. 9 It is therefore significant to find the methods for alleviating or preventing such violent discharge in the dielectric materials. In recent two decades, the nanoparticles have been widely used to improve electrical properties of the dielectrics such as suppressing space charge accumulation, [10][11][12] improving initial voltage of insulation polymer treeing, 13 enhancing electrical breakdown strength.…”

Fast discharge of numerous space charges in dielectric materials can cause space charge breakdown. This letter reports the role of nanoparticles in affecting space charge breakdown of nano/polymethyl methacrylate composites. Space charge distributions in the composites, implanted by electron beam irradiation, were measured by pressure wave propagation method. The results show that the nanoparticles have significant effects on the isothermal charge decay and space charge breakdown in the nanocomposites. The resistance to space charge breakdown in the nanocomposites is attributed to the combined action of the introduction of deep trapping states and the scattering effect by the added nanoparticles.
