The frequency-dependent ac conductivity and permittivity are examined as a function of volume fraction of carbon-based filler. The measured electrical properties and their frequency dependency are evaluated on the basis that such composites can be considered as a network of resistors and capacitors, whereby the resistors represent the conductive component (CNT or TRGO) and the capacitors are the insulating component (epoxy matrix). Differences observed between the frequency-dependent electrical properties of the CNT-epoxy and TRGO-epoxy composites are explained in terms of the different electrical conductivities of the CNT and TRGO phase. © 2014 IUPAC & De Gruyter.en1365-307520145765774de GruyterCarbon nanotubesElectrical networksElectrical propertiesGraphene oxideManufactureNanocompositesNMS-IXPermittivityChemieConference Paper10.1515/pac-2013-1207Other
