Dielectric and electrical properties of radiation-cured epoxy are investigated in various conditions of electric field and temperature for different initiator content. The impact of the onium salt initiator is particularly considered due to the formation of ionic species that can impact the electrical properties. Dielectric spectroscopy performed in the temperature range -80 °C to +200 °C and the...
Radiation-cured epoxy networks are promising materials for a number of applications for which both high mechanical and dielectric strength are required. In this work, epoxy materials are manufactured via a cationic mechanism which requires an initiator, generally an onium salt, to trigger the cross-linking process under ionizing radiation. It has been established that both the nature of initiator...
Radiation-cured epoxy and acrylate-based materials are used in a number of applications where curing under ionizing radiations is preferred to the classical thermal curing process. Because mechanical properties are often the key features in these applications much less attention has been paid to their electrical properties. We report on the dielectric properties of two classes of radiation-cured materials...
