Abstract

Hybrid materials polyurethane films were prepared with different content of carbon, and carbon/zinc oxide as filler components in polyurethane matrix. The films were deposited on low carbon steel plate using high volume low pressure (HVLP) method. To observe corrosion resistance of the films, the samples were examined by salt spray method. Dielectric properties were obtained by resistivity valued method. Thermal resistance was investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) used to see functional groups and phase composition of carbon and zinc oxide (ZnO) in polyurethane matrix. After ZnO and carbon addition, we observe changes in surface morphology and more resistant to corrosion. Dielectric test showed that only carbon dispersed in polyurethane matrix have higher dielectric value at higher frequency. TGA and DSC confirmed composites with carbon and ZnO as filler that has highest temperature decomposition.
