【摘要】 <正>目前大量有关聚丙烯/蒙脱土(PP/MMT)纳米复合材料研究显示,加入聚丙烯接枝马来酸酐(PP-g-MA)有助于蒙脱土的分散和剥离,并且提高了聚丙烯的部分力学性能,但是PP的韧性改善不多。本文通过PP-g-MA与PEG反应合成了聚丙烯接枝聚乙二醇(PP-g-PEG),更多还原

【Abstract】 Polypropylene(PP)/montmorillonite(MMT) nanocomposites were prepared by melt blending technique thought a new route:maleic anhydride grafted PP(PP-g-MA) directly reacted with poly(ethylene glycol)(PEG),then blended with PP and MMT.Because of the typical intercalated structure,mechanical properties of the nanocomposites were improved significantly as compared with pure PP.It was found that the izod-notched impact strength and elongation at break were significantly enhanced.The izod-notched impact strength and elongation at break of PP nanocomposites increased by 80%and 52%compared with those of pure PP.The tensile strength of PP was also improved.更多还原
