TL;DR: In this article, the ability of different geometrical models to describe the experimental relative permeability data is discussed, which leads to the conclusion that it is necessary to consider the polydispersity of the impermeable filler shapes and to take into account the presence of surfactant located at the inorganic surface to appropriately model the transport properties of the nanocomposites in a large range of nanoclay contents.

TL;DR: In this article, the gas barrier properties of the different composite systems were discussed both as a function of the clay dispersion and of the matrix/clay interactions, the highest barrier properties were obtained for an exfoliated morphology and the highest grafting density.

TL;DR: Amorphous nanocomposite films were prepared from melt-blending of polylactide (PLA) and an organo-modified montmorillonite (O-MMT) as discussed by the authors.

TL;DR: The water sorption of chitosan has been studied at 20 °C in this paper, where the water transport is governed by a Fickian process for relative humidities lower than 0.4 and in that range of partial pressures, the diffusion coefficient is concentration-dependent.

TL;DR: In this article, a mixture of intercalated and exfoliated structures was formed by the addition of pristine montmorillonite, whereas an aggregate structure was obtained with organoclay.
