dc.description.abstract | Dynamically vulcanized thermoplastic polyurethane (TPU)/millable polyurethane (MPU) blend nanocomposites, simple TPU/MPU blend nanocomposite, and TPU nanocomposite with 3 parts per hundred (phr) of organoclay were melt compounded in an internal mixer. Interfacial interactions between the organoclay and polyurethanes were examined by Fourier transform infrared spectroscopy, X-ray diffraction, and transmission electron microscope analysis, which revealed that the dispersion of organoclays significantly improved with increasing TPU content in the TPU/MPU blends and dynamic vulcanization process. Tensile test and dynamic mechanical analysis showed that the mechanical properties are improved with the TPU content in the TPU/MPU blends and dynamic vulcanization process. Both hardness and tension set of the samples decreased with increasing MPU content in the TPU/MPU blends. Thermal stability determined by thermo-gravimetric analysis revealed that it increased with increase in TPU concentration in the samples. Differential scanning calorimetry study showed that the glass transition temperature (T-g), melting temperature (T-m), and melt crystallization temperature (T-c) of the samples were significantly affected by the blend composition and dynamic vulcanization. Dynamic melt rheology of the nanocomposite samples in the molten state revealed a pseudo solid-like behavior as well as an enhanced shear thinning behavior, and the variation of the rheological properties are well correlated with blend compositions and morphology of the nanocomposites.
