Influence of the fullerene derivatives and cage polyhedral oligomeric silsesqiuoxanes on 3-aminopropyltrimethoxysilane based hybrid nanocomposites chemical, morphological and electrical properties

► The combination of the surface-sensitive spectroscopic and microscopic methods. ► Fractal-shaped clusters formation. ► PCBM and POSS dopants decrease the dielectric constant of the produced composites.
