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.
