Abstract

This paper presents preliminary studies on two aspects of nylon-based nanoclay composite films: their out-of-plane tearing fracture resistance and moisture diffusion characteristics. Attempts to analyze the out-of-plane tearing fracture based on the essential work of fracture analysis will be presented. Also, theoretical modelling of the permeability of these polymer nanocomposites is also presented which takes into account the degree of exfoliation, orientation, aspect ratio and volume fraction of the nanoclay sheets; crystallinity of polymer matrix; and the affinity of polymer and clay with the diffusing species. Comparisons with published permeability data are given.
