| Summary: | 碩士 === 淡江大學 === 化學工程學系 === 88 === The study dealt with the investigations of the rheological, dynamic properties of the blends of Nylon composites and MPE. On the rheological behavior, we used the plate-and-plate rheometer to measure the steady and dynamic properties of the Polymer blends. About the morphological analysis, we used the scanning electron microscope to study the influences of the morphology of the blends on melt rheological properties.
According to experimental results, we found that shear viscosity increase with concentration of the MPE. Moreover, the higher is the concentration of the MPE, the less obvious is the shear-thinning. In addition, we found that the storage modulus increase with concentration of the MPE. The lower is the concentration of the filler, the smaller is the relative modulus ratio.
On the morphology, we found that the dispersed MPE phase in spherical shape. When it is deformed in shear, the recovery of the droplets can increase the shear viscosity and storage modulus of the polymer blends.
