| Summary: | 碩士 === 國立臺灣大學 === 材料科學與工程學研究所 === 92 === Effects of PEO-modified-clay and molecule weight of PEO absorbed on the clay surface on the crystallization and morphology of PEO/clay and PMMA/PEO/clay composites were studied. The structure of clay of these composites was characterized by WAXD. The thermo degradation was studied by TGA. Then the spheruilitic growth rate, density of nucleus, and morphology of spherulite were studied by POM. Utilizing the DSC, the overall crystallization rate was studied and compared with the results from POM. The experiment results showed that clay decreased the growth rate of spherulite and increased the density of nucleus. The molecule weight of PEO absorbed on the clay surface would influence the thermal properties, kinetic of crystallization, and morphology of spherulite.
