Surface morphology changes in gamma-irradiated silicone rubber alumina nanocomposites were studied using AFM. Further, dielectric characteristics, gamma irradiation effects on space charge, and charge trap properties were explored. Corona aging impact on surface condition was assessed through various methods, including AFM and MRSD. Dynamics of surface charge, charge trap, and space charge in silicone rubber nanocomposites post-corona aging and recovery were investigated. Aging's impact on elemental and plasma temporal properties was studied using LIBS technology.
