DMA properties of semiconductive composites in power cables by dual filler system

This paper applied DMA to investigate the storage modulus, loss modulus, and Tandelta of nano-composite materials using a dual filler system that is fabricated by using different contents of CNT and CB for EEA. As a result, although the glass transition temperature of such nano-composite materials did not show changes in the temperature according to the change in applied contents, the storage modulus, loss modulus, and Tandelta increased according to the increase in applied contents. It is considered that the polymer chains were aligned according to the application of CNT, which has a large aspect ratio, as a reinforcing agent and there existed a certain crosslinking structure due to the increase of mechanical interlocking in resin.
