Carbon-Polyurethane Composites were prepared from polyetherurethane (PPG-TDI-BD) and electrical conductive fillers. The fillers used were graphites, carbon black (Ketjen EC and BP-2000), carbon fiber, CuCl2-, (Fecl3-) graphaite intercalation compounds (GIC), and nickel powder. Mechanical properties, Tg, thermal stabiltiy, and electrical conductivity of these composites were studied. The GIC which is unsatable in air was satablized in the polyurethane matrix. The electrical conductivity of CuCl2-PU composities was slightly better than that of graphite - PU. The conductivity of carbon black (5～15wt%) -PU showed 106～103 Ωcm. Carbon fiber reinforced mechanical properties and thermal stability of the PU composites. Carbon fiber-PU composites may be used as shielding materials of electromagnetic interference.
