Abstract
This paper investigates the electrothermal behavior of industrial films made by graphene nanoplatelets (GNP) mixed to polymers, with the final goal of deriving their equivalent electrical resistivity and thermal emissivity. The two parameters are identified by means of suitable models and experimental characterization with ad-hoc test-fixture. The materials analyzed here are thin strips of the order of 1×10 cm, with a thickness of 75 µm, both made by pressed GNPs, mixed to a small quantity of polymeric binders. An analytical model to describe the temperature-dependence of the electrical resistivity is proposed. The impact of the binder percentage (5% or 20%) on the electrical resistivity and thermal emissivity is also studied.
