Abstract

The present invention relates to a semiconductive polyolefin composition comprising graphene nanoplatelets. It also relates to a semiconductive polyolefin composition comprising the combination of graphene nanoplatelets and carbon black. Moreover, the present invention is related to a process for producing the semiconductive polyolefin composition as well to the use of the semiconductive polyolefin composition in a power cable. Further, the invention is also related to an article, preferably a power cable comprising at least one semiconductive layer comprising said polyolefin composition.
