摘要

采用熔体插层法制备聚丙烯（PP）/有机黏土（OMMT）纳米复合材料。XRD和TEM的测试结果表明，采用熔体插层法制备的PP/OMMT复合材料是剥离型纳米复合材料。力学性能实验结果表明，相容剂的加入提高了PP与OMMT之间的相互作用，使其各项力学性能都得到了提高;PP/OMMT纳米复合材料的各项力学性能在有机黏土含量较小的情况下，就可以有较大幅度的提高;与纯PP相比，相容剂含量为10 phr、有机黏土用量为1 phr的聚丙烯基纳米复合材料具有最好的各项力学性能。

Abstract

Polypropylene (PP) / organomontmorillonite (OMMT) nanocomposites were prepared by the melt intercalation method.The dispersion of clay was investigated by transmission electron microscopy (TEM) and X-ray diffraction (XRD).TEM images and XRD patterns demonstrated that the dispersion structure was extremely disordered and close to exfoliated structure in these nanocomposites.The experimental results showed that the mechanical properties of nanocomposites were improved rapidly at a very low content of clay.More importantly

the mechanical performance of PP/OMMT nanocomposites was improved further by importing the compatilizer

which was beneficial to improving the interfacial interaction between PP and OMMT.Compared with pure PP

when the content of the compatilizer was 10 phr

and OMMT was 1 phr

the prepared PP/OMMT nanocomposites possessed the best mechanical properties.
