摘要：

The polyurethane (PU) nanocomposites were prepared using organomodified sepiolite (organo-Sp) by in situ polymerization method. The clay was modified with three different organic modifiers such as gamma-aminopropyltriethoxylsilane (KH550), hexadecyltrimethylammonium bromide (CTAB) and lauric acid (LA). The morphology and the dispersion of organo-Sp in polyurethane were characterized by scanning electron microscope, transmission electron microscope and Fourier transform infrared spectroscopy. The influence of organo-Sp on the tensile properties, water resistance and swelling rate of polyurethane composites was studied. The results showed the properties and structure of polyurethane nanocomposites were related to the kind of organic modifier. (C) 2010 Elsevier B.V. All rights reserved.
