将功能化多壁碳纳米管(f-MWCNTs)引入到不相容的聚丙烯/乙烯-醋酸乙烯共聚物(PP/伊娃)共混体系中。通过改变f-MWCNTs的含量,制备了两种不同的复合材料,一种(PP/伊娃=80/20)为典型的海岛型结构,另一种(PP/伊娃=60/40)为共连续型结构。冲击韧性测试表明,f-MWCNTs的加入显著提高了PP/伊娃共混物的断裂韧性。结果表明,PP/伊娃(80/20)体系中f-MWCNTs存在局部的“单网络结构”,而PP/伊娃(60/40)体系中f-MWCNTs和伊娃相存在“双网结构”,后者是复合材料断裂韧性得到较大提高的原因。
Functionalized multiwalled carbon nanotubes (f-MWCNTs) have been introduced into immiscible polypropylene/ethylene-co-vinyl acetate (PP/EVA) blends. Two different compositions, one (PP/EVA=80/20) exhibits the typical sea-island morphology and the other (PP/EVA=60/40) exhibits the cocontinuous morphology, have been prepared with different contents of f-MWCNTs. The impact measurement shows that f-MWCNTs induce the great improvement of fracture toughness of cocontinuous PP/EVA blends. The results based on the morphologies and the rheological properties of the composites suggest that, a local “single-network structure” of f-MWCNTs exists in PP/EVA (80/20) system whereas a “dual-network structure” of f-MWCNTs and EVA phase exists in PP/EVA (60/40) system, and the latter structure accounts for the largely improved fracture toughness of the composites.
