Microwave behaviour comparison between different carbon based materials in Epoxy resin composites

Because their low weight and high performance, polymer composite are an important material for new applications studies. They have the possibility to tune a particular proprieties (e.g. electrical or mechanical) using different kind of filler and percentage. Carbon fillers are the most quoted filler in composites where tuning electrical proprieties are the target. Different carbon filler are present in the market. From cheaper (e.g. carbon black), to eco-friendly (e.g. Biochar) or more sophisticate (e.g. carbon nanotubes). Here in this work we studied the microwave performance of these different kinds of carbon filler dispersed in Epoxy resin.
