Results of broadband dielectric spectroscopy (20 Hz–1 MHz) of a novel polymer composite based on onion-like carbon (OLC) are presented. The measurements were performed by cooling and heating in a wide temperature range (240 K–420 K). After heating the dielectric permittivity strongly increases, β relaxation slows down while γ relaxation becomes negligible. The observed behaviour of relaxations suggests that dielectric properties of presented composite without additional heating are strongly influenced by extrinsic humidity. The increase of the OLC fillers concentration (up to 1 wt%) has been found to strongly increases the glass transition temperature of OLC-based polymethyl methacrylate (PMMA) composite, however, an effect of the OLC inclusions on the beta transition of the given nanocomposites is less expressed.
