Abstract:	本研究從事mPE/mPE-g-silane/clay奈米複合材料之製備，使用DCP (Dicumylperoxide)為起始劑，DBTL(Dibutyin Dilaurate)作為催化劑，VTEOS(Vinyl TriethoxySilane)當交聯劑，使用的mPE為Dow的EG系列(EG 8003)，製備mPE-g-silane為相容劑，在混煉機中先進行mPE接枝矽烷交聯劑，再和mPE/clay掺混，最後熱壓成薄片，以70℃水浴進行水交聯。抗張實驗中發現，clay 20A系統的隨著濃度上升楊氏係數隨之上升，增加了材料的剛性。clay 20A確實分散於材料中並達到補強的效果。 Metallocene polyethylene-octene elastomer (mPE)/clay nanocomposites are obtained and studied by using mPE-g-silane as a compatibilizer. Metallocene polyethylene was grafted with vinyl triethoxy silane first and then followed by the mixing of which with mPE and clay. The crosslinking reaction was conducted at 70℃ in the presence of water. Through tensile test, Young's modulus was increased with increasing clay content. This was attributed to the high surface area between the mPE and the clay.
