| Abstract: |
| The influence of hydrothermal aging on the crosslink density，water absorption，physical properties，electrical properties and thermal stability of silicone rubber/manganese-zinc ferrite composites was investigated.The results showed that，as the hydrothermal aging time was prolonged，the crosslink density and water absorption increased，Shore A hardness，the modulus at 100% elongation and tensile strength increased，elongation at break decreased，surface resistivity，volume resistivity and dielectric strength decreased，dissipation factor increased，complex permittivity decreased and then increased，thermal stability decreased quickly at the initial stage of hydrothermal aging，but decreased only a little more at the later stage. |
