英文摘要	A cellular segregated graphene network within poly(vinylidene fluoride) (PVDF) was constructed through hot compression of PVDF/graphene core-shell particles, which were fabricated via assembly of graphene oxide nanosheets (GrONs) on acrylamide-grafted PVDF particles and succeeding reduction of GrONs. The assembly was achieved by flocculation of GrONs, utilizing the salting-out effect of GrONs aqueous colloid. After reduction of the GrONs and the following hot compression of PVDF/graphene core-shell particles, the final composites exhibited an ultralow percolation threshold of 0.031 vol%, which can be attributed to the excellent construction of the cellular segregated graphene networks and exclusion effect of the bulky PVDF zones.
