Recently, research on hybrid materials of Polyurethane/Carbon/Nanoclay are challenging because of their applications. In this study, these materials were fabricated with various amounts of carbon and organoclay (1, 3, and 5) wt.%). The samples were characterized by thermogravimetry analysis, differential scanning calorimetry, optical microscope, RLC meter, Fourier transform infrared spectroscopy (FTIR) and salt spray test. The results showed that the samples with 5 wt.% carbon/organoclay have higher dielectric constant. Thermal behavior of the samples depends on the content of the filler. Salt spray test showed that the samples with 1 wt.% carbon/organoclay have higher corrosion resistance.
