| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 94 === In this study, the EPDM/organic clay nanocomposites were prepared by melt intercalation. The effects of nanoclay in these EPDM/clay nanocomposites were investigated on their structures, mechanical, thermal and electrical properties. The structures of nanoclay in these EPDM/clay nanocomposites were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The mechanical and thermal properties were measured by Universal Tensile Testing Machine and Thermogravimentric Analyzer (TGA). The glass transition temperature was measured using Dynamic Mechanical Analyzer (DMA). The volume resistivity were measured by resistivity test meter.
The nanocomposites exhibited great improvements in the tensile strength, elongation, and tensile modulus. The silicate layers of the clays were exfoliated and dispersed uniformly in the EPDM matrix. The glass transition temperature of EPDM/clay composites rose with increasing nanoclay content. The thermal degradation temperature was also increased by the increase of exfoliated nanoclay. The volume resistivity was also improved.
