Electrospinning is an efficient technique for the fabrication of polymer nanofibers. The charges inside the polymer jet tend to repel each other so as to stretch and reduce the diameter of the polymer fibers. By rotating the collector at a fast angular speed, nanofibers with specific orientation can be obtained. In this study, nanofibers of Polyethylene oxide (PEO) with carbon black were prepared by electrospinning. PEO was dissolved in a mixture of water and ethanol. PEO is known as an electrolytic polymer. With the blending of carbon black powders, its electrical properties along the fiber direction were investigated. The fiber morphology and characteristics were studied by SEM and polarized FTIR.

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 biochar-based composite in function of pressure applied. The results obtained were compared with carbon black and carbon black composites. We demonstrated that, even if the coffee biochar had less conductivity compared with carbon black in powder form, it created composites with better conductivity in comparison with carbon black composites. In addition, composite mechanical properties were tested and they generally improved with respect to neat epoxy resin.
