Nanocomposites based on (PU/PVC) polyurethane (PU) and poly (vinyl chloride) (PVC) loaded with low contents of multi walled carbon nanotubes (MWCNTs) were prepared using solution casting technique. The composition and structure of blend and nanocomposites were characterized by X-ray diffraction (XRD),Transmission electron microscope (TEM), and Differential scanning calorimetry (DSC). The X-ray study indicated that decrease crystallinity of polymer blend after addition of carbon nanotubes due to interaction between carbon nanotube (CNT) and the polymer matrix in the nanocomposites. Thermal stability was studied by Differential scanning calorimetry (DSC) analysis. The obtained data from these study described that the glass transition temperature (Tg), melting point (Tm) and degradation temperature (Td) of the samples were increased with an increase of different concentrations of MWCNTs. The behavior of thermal stability were enhanced. Mechanical properties were calculated by tensile universal testing machine. All results data showed well dispersed of MWCNTs in polymer matrix at all weight percentages
