| Abstract: | 本研究使用混煉機以熔融插層法製備茂金屬聚乙烯(mPE)/黏土奈米複合材料，並使用馬來酸酐接枝茂金屬聚乙烯(mPE-g-MA)作為相容劑。以DCP作為交聯劑進行交聯，比較交聯前後各項性質的改變。
經X光繞射分析(XRD)顯示，黏土與mPE混煉後其層間距離些微增加，而相容劑mPE-g-MA能幫助黏土的分散，有效的增進黏土的層間距離(d-spacing)；經機械性質撕裂測試發現，黏土的摻入可有效提升材料的撕裂強度，使用mPE-g-MA能使黏土分散性變佳，但由於其本身性質的影響，未交聯之樣品其強度反而降低，但交聯後之樣品因為相容劑影響減小，因此黏土分散提高確實讓強度提升；黏土的摻入也提升了材料的耐熱性，但黏土含量超過5 phr其熱重損失溫度反而下降。
Metalloncene polyethlene (mPE)/clay nanocomposite were prepared by melt intercalation method using a mixer. mPE-graft-maleic anhydride(mPE-g-MA) was used as a compatibilizer. DCP was used for curing.
X-ray Diffraction(XRD) revealed that the d-spacing of clay platelets increased after blending and formed intercalated nanocomposite. mPE-g-MA could increase the dispersion of clay platelets and expanded its spacing. The mechanical properties were enhanced observed by tear tests. mPE-g-MA can increase the tear strength increase after curing. The thermal resistance was increased in the presence of clay, but it decreased if clay content was over 5 phr. |
