英文摘要	By reducing the attraction between the platelets of octaclecylammonium chloride modified montmorillonite (OMMT-C18) via pre-intercalation of maleated polypropylene (MAPP), OMMT-C18 was exfoliated in thermoplastic polyurethane (TPU) matrix during melt-mixing. Wide angle X-ray diffraction, transmission electron microscopy and thermogravimetric analysis were used to investigate the microstructure of TPU nanocomposites. Three factors (including introducing sequence, the kind and the content of MAPP) showed important effects on the dispersion degree of OMMT-C18 in TPU matrix. The results confirmed that the pre-intercalation of MAPP was necessary for the exfoliation of OMMT-C18; however, the role of MAPP in TPU nanocomposites was different from that in polypropylene nanocomposites. In addition, the investigation on the morphology evolution of TPU nanocomposites showed that shear force played a key role in the formation of exfoliated TPU nanocomposites. TPU nanocomposites with exfoliated structure showed better properties compared with TPU and its nanocomposites with intercalated structure. (C) 2009 Elsevier Ltd. All rights reserved.
