Development of Coffee Biochar Filler for the Production of Electrical Conductive Reinforced Plastic
In this work we focused our attention on an innovative use of food residual biomasses. In particular, we produced biochar from coffee waste and used it as filler in epoxy resin composites with the aim to increase their electrical properties. Electrical conductivity was studied for the biochar and bi...
