Segmented polycarbonatediol polyurethane (PUPH) has been synthesized and modified with different
amounts of graphite conductive filler (from 0 to 50 wt%). Thermal and dynamical thermal analysis of
the composites clearly indicates changes in the polyurethane relaxations upon addition of graphite.
Broadband dielectric spectroscopy has been used to study the dielectric properties of the (PUPH) and
one composite in the frequency range from 10−2 to 107 Hz and in the temperature window of −140 to
170 ◦C. Relaxation processes associated with different molecular motions and conductivity phenomena
(Maxwell–Wagner–Sillars and electrode polarization) are discussed and related to the graphite content
