Tóm tắt

The PVC/TiO2 nanocomposite samples were structurally characterized by scanning electron microscope that ascertains its polymer nanocomposite nature. The dynamic mechanical response, i.e., storage moduli and phase transition temperature accompanied by temperature have been studied through Dynamic Mechanical Analyzer (Tritec 2000 DMA). The intrinsic viscosity and phase transition activation energy is resolute in using these data. The results reveal that TiO2 nanoparticle dispersion in PVC causes prominent enhancement in observed properties. However, the enhancement depends on proportion of nanoparticles.
