Abstract

The analysis of the transport properties of water vapor through composites composed of polylactides (PLA) and a montmorillonite modified with bis-(2-hydroxyethyl)methyl tallowalkyl ammonium cations (MMT) was reported. It was observed that the sorption curves of water vapor in all the samples follow the dual-sorption behavior. The exfoliated nanocomposite showed a large decrease in the thermodynamic diffusion parameters, D0 value, being lower by about two orders of magnitude. The exfoliation of the inorganic component in the continuous polymeric phase can be the most important factor to improve the barrier properties of the material to water vapor.
