Résumé
Recycling route toward electro-active silicone composites has been explored. We studied the dependence of the E-J characteristics on the aggregate content in the polymer matrix. Formulations with 35 vol.% MOV aggregates in the 200-375 µm range exhibit reliable nonlinear behavior with a switching voltage of 175 ± 30 V/mm. This opens a way to valorize varistors based on zinc oxide (ZnO) ceramics.
