One of the methods that can improve the mechanical properties of polymers is blending, for this purpose polyvinlydenefloride (PVDF) was blended into polyurethane PU with different weight fractions (10,30,70.100) % using solution casting method and then PU/ PVDF blends were compression molding at 200 °C. Fourier transform infrared spectroscopy (FTIR), Atomic force microscope (AFM), Differential scanning calorimetry (DSC), and mechanical properties (hardness and impact test) have been used for polymeric blends characterization. The results of FTIR tests showed that there is no change occurring when PU blended with PVDF. Moreover, results of fracture toughness show that the impact strength of PU/PVDF blends was increased by (5.25 %) as the amount of PVDF increased, while the shore D hardness decreased by 59.3%. The AFM results showed that the addition of PVDF has lower the surface roughness of blends. DSC analysis illustrates that the melting temperature of the blends PU/PVDF slightly increased when the amount of PVDF increased from (10 to 70) %, while the melting enthalpy decreased for TPU/PVDF blends consequently the crystallinity decreased as PVDF content increased.
