ELECTRICAL CHARACTERIZATION FOR DIFFERENT CARBON BASED POLYMER COMPOSITES

Electrical properties of polymer composites based on carbon filler are a hot spot in recent years [1,2]. As sp2 hybridised carbon is a good conductor due to the mobility of electrons in its outer valence shells, can be used as filler material. The consequent possibility to tune electrical properties of composites lead to new applications for them. While carbon naontubes are the most commonly used form of carbon in composites, less expensive and more environment friendly carbon-based fillers derived from recycled materials are attracting more and more interest. In this work, we will compare the electrical properties (permittivity and electrical conducibility) of polymer filled with CNTs and polymer filled with alternative carbon fillers derived from organic residues.
