    Abstract: 本研究中PP/Metallocene polyethylene/clay奈米複合材料(PP/mPE/clay)之製備,使用DCP(Dicumyl peroxide)為起始劑,DBTL (Dibutyltin dilaurate)作為催化劑,VTEOS (Vinyl triethoxy silane)當交聯劑,在混煉機中先進行mPE接枝矽烷交聯劑,再和clay掺混,然後與PP進行掺混,最後熱壓成薄片,以70℃水浴進行水交聯。奈米複合材料掺入比例以mPE為100 phr,clay為2、5、9 phr,觀察添加不同clay比例時交聯和未交聯對材料的機械性質,熱性質和微觀構造的影響。
    以廣角X光繞射分析儀(X-ray diffraction, XRD)與穿透式電子顯微鏡(Transmission electron microscopy, TEM)觀測結果顯示,黏土以插層型結構分散於基材中,形成奈米複合材料。而傅立葉轉換紅外線光譜儀(FT-IR)進行成份分析,觀察樣品中silane、clay的特徵官能基,並觀察clay含量增加時,1104cm-1特徵吸收峰強度轉弱,但在1018 cm-1和1045 cm-1特徵吸收峰強度轉強。經熱重分析儀(TGA)顯示,添加clay皆能提升其5 wt %重量損失溫度、50 wt %重量損失溫度。經抗張測試與撕裂測試發現,添加clay之後,交聯系統之機械性質比未交聯系統來的好。
