摘要：

The barrier properties of two sets of model epoxy nanocomposites with variations in nanoplatelet exfoliation level and aspect ratio have been investigated. The results show that both the exfoliation level and aspect ratio of nanoplatelets have a significant effect on the nanocomposite barrier properties. The results have also been correlated with a number of semi-empirical and physical models. It is found that both Gusev-Lusti's 3D model and Nielsen's 2D model give good correlation with experimental findings. Implication of the present study for barrier properties improvement of polymer nanocomposites is discussed. (C) 2008 Elsevier B.V. All rights reserved.
