A tailored approach to optimize the barrier properties of Poly(lactic acid) nanocomposites for food contact purposes
Abstract
A new kind of barrier materials, so called “chaotic” materials and involving interactions with nano-charges, is presented. By contrast with conventional use of nano-clays, the sought effect consists not in increasing the tortuosity to penetrants but in increasing the dwelling times of solutes around accessible clays designed on purpose. The paper reviews several theoretical models that explain why effective diffusion coefficients (D) decay due to entropic trapping. The physical concepts are applied to a simple material made of a deactivated glass column filled with montmorillonites and exposed to several gas phases enriched in organic solutes. In this simple physical model, a carrier gas replaces the polymer so that molecular effects can be visualized and analyzed almost in real time with a simple flame-ionization detector. The future directions to combine a bio-sourced material (PLA) and montmorillonites are outlined.
