通过应用与挤出机连接的层压倍增元件（LME）组件，制备了三种聚合物共混物：尼龙6/等规聚丙烯、滑石粉/乙烯1-辛烯共聚物和炭黑（CB）/丙烯乙烯共聚物。形态观察表明，这些LME不仅可以对熔体提供双向拉伸力，导致分散相取向，而且还可以使这些颗粒的分布变得更加均匀。还分别研究了拉伸、阻隔或电性能，并展示了 LME 形态的发展。结果表明，层压-倍增挤出系统是获得具有特定形态和分布的聚合物复合材料的有用工具。聚合物。 COMPOS., 2012。(c) 2012 年塑料工程师学会
Three kinds of polymeric blends: nylon 6/isotactic polypropylene, talc/ethylene 1-octene copolymer, and carbon black (CB)/propyleneethylene copolymer are prepared by applying an assembly of laminating-multiplying elements (LMEs) connecting with an extruder. The morphological observations illustrate that those LMEs may not only provide biaxial stretching force on the melt, leading to the orientation of dispersed phase, but also make the distribution of those particles become more even. The tensile, barrier, or electrical properties are also investigated, respectively, and demonstrate the development of morphologies in LMEs. Results suggest that the laminating-multiplying extrusion system is a useful tool to obtain polymeric composites with specific morphologies and distribution. POLYM. COMPOS., 2012.
