    Dielectric analysis of a novel polymer composite based on onion-like carbon (OLC) has been carried out by varying the temperature between 240 and 460 K within a wide frequency range (20 Hz-1 MHz). A small effect of the OLC inclusions on the beta transition of OLC/polymethylmethacrylate (PMMA) composite has been observed, which indicates a weak affinity of the OLC to the host matrix. At the same time, an increase in concentration of the OLC has been found to strongly influence the glass and melting temperatures of the nanocomposites. These structural properties of the OLC/PMMA composite materials should be taken into account when a new family of effective wide-band electromagnetic materials are designed and fabricated.
