Here, the morphology and electron-transport properties in reduced graphene oxide (rGO)-filled composites with a segregated structure based on polyvinyl chloride (PVC), poly(vinylidene fluoride-co-tetrafluoroethylene) (P(VDF-TFE)), and ultrahigh-molecular-weight polyethylene (UHMWPE) are studied.

The electrical conduction of the composites and the rGO-paper occurs through the same hopping conduction mechanisms within the wide temperature range, which allows to use the composites in applications where pure rGO is considered. Owing to thicker rGO layers open to the environment, PVC- and P(VDF-TFE)-based composites are more attractive, rather than the UHMWPE ones, in applications where layered materials are needed, for example, in lithium-ion batteries or supercapacitors.
