摘要: Poly(ethylene terephthalate) (PET)/clay nanocomposites (PCNs) with N-methyl diethanol amine (MDEA)-based organoclays are synthesized by using in situ polymerization. Four kinds of MDEA-based materials prepared and used as organifiers pristine montmorillonite. The clay treated the has a d-spacing range that is about 14–21 A. PCNs these characterized wide-angle X-ray diffraction, scanning transmission electron microscopy, atomic force capillary rheometry, tensile barrier testing. form an intercalated delaminated structure. well-stacked nanoclays broken down into small pieces PET matrix thickness bundle decreases to 20 nm. melt viscosity strength increases only 0.5 wt % clay. In oxygen testing, PCN 1 well-dispersed organoclay shows twofold higher property than pure PET. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 1262–1271, 2007
