A Study on the Dielectric Properties and Viscoelasticity of EEA/Acetylene Black Composites

EEA/Acetylene Black 복합체의 유전특성과 점탄성에 관한 연구

To measure electrical properties and viscoelasticity of semiconducting materials in power cable, we have investigated dielectric properties and modulus of EEA/acetylene black composite showed by changing the content of acetylene black. The permittivity from experimental result was increased, while tan6 was decreased by an increment of the content of acetylene black. The modulus of specimens was increased according to a increment of a acetylene black content. And modulus was rapidly decreased at the glass transition temperature. The tan$\delta$ of specimens was decreased according to a increment of a acetylene black content.
