During the first year of the project the main purpose was to choose, purchase and develop investigated materials: epoxy resin and at least two carbon nanofillers (nanotubes, nanofibres and/or graphene). The most promising material solution and the most optimal processing route were chosen and reported. Then two sets of epoxy and NC specimens were developed during Mobilities#2-3 to partner organization, Institute for Polymers, Composites and Biomaterials (Portici, Italy). The test specimens of epoxy and NC were subjected to environmental ageing: water absorption at 70 °C until equilibrium water content and heating at 70 °C, then freezing at ap. -20 °C to evaluate the most environmentally stable NC configuration. Based on preliminary results (without results after freezing), the most environmentally stable NC was epoxy filled with 0.1 wt. % of CNT/CNF, which had the lowest effect of temperature and moisture on thermal and electrical conductivities, along with the lowest equilibrium water content and diffusivity.
