In this work, nanopowders of graphene oxide (GO) and functionalized graphene (G*) have been mixed with low-density polyethylene (LDPE) to fabricate samples with low filler weight ratio. A peculiar fabrication method was utilized, which consisted of ball-milling followed by thermal pressing. Electrical properties like resistance to erosion due to partial discharge (PD), and breakdown values were detected and the results were compared with those obtained on the neat LDPE. It is highlighted that the addition of G*, in particular, improves significantly both resistance to PD activity and the electric strength of LDPE specimens.

Abstract
In this work, nanopowders of graphene oxide (GO) and functionalized graphene (G*) have been mixed with low-density polyethylene (LDPE) to fabricate samples with low filler weight ratio. A peculiar fabrication method was utilized, which consisted of ball-milling followed by thermal pressing. Electrical properties like resistance to erosion due to partial discharge (PD), and breakdown values were detected and the results were compared with those obtained on the neat LDPE. It is highlighted that the addition of G*, in particular, improves significantly both resistance to PD activity and the electric strength of LDPE specimens.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
