ΣΥΝΤΟΜΗ ΠΕΡΙΛΗΨΗ
In the present study, the effect of particle size upon the dielectric properties of polyurethane/boehmite alumina nanocomposites was investigated in a wide range of frequencies and temperatures. Three distinct relaxation modes were recorded in the examined spectra of all systems, they were attributed to interfacial polarization, glass transition (α-relaxation) and motion of polar side groups (β-relaxation).
