Dielectric Properties of Compatibilised EPDM/Silicone rubber Nanocomposites

Abstract

EPDM/Silicone rubber nanocomposites are prepared by incorporating various phr of organically modified montmorillonite (OMMT) nanoclay onto compatibilised and uncompatibilised EPDM/Silicone rubber blends using two roll mill. Compatibilisation of EPDM and Silicone rubber blend is achieved through insitu grafting of silane onto EPDM during mixing of rubbers. Effect of OMMT content and compatibilisation of blend system on electrical, mechanical and thermal properties of the nanocomposites are investigated. The results obtained for various properties indicate that the compatibilised EPDM/Silicone rubber nanocomposites have improved dielectric, mechanical and thermal properties compared to that of uncompatibilised blend nanocomposites. It is observed that, the addition of OMMT upto 5 phr onto both compatibilised and uncompatibilised blends of EPDM/Silicone offers significant improvement in the above mentioned properties. Increasing content of OMMT onto the blends cause marked enhancement in thermal stability of the nanocomposties. Transmission electron micrographs shows the compatibility between EPDM and silicone rubbers in the blend and the exfoliation of OMMT layers in the matrix phase. The present work reveals that the compatibilised EPDM/ Silicone/ OMMT nanocomposite can be a better candidate for high voltage electrical insulation due to its enhanced dielectric, mechanical and themal characteristics.
