The modeling of diffusion through nanocomposite membranes has recently been studied extensively. However, most studies fail to develop models that can accurately describe mass transport in terms of a reasonable number of physically significant parameters. Here, the diffusion process will be modeled by applying the generalized bracket/General Equation for Non-Equilibrium Reversible and Irreversible Coupling (GENERIC) formalism. Two main systems are considered. First, the transport of a simple gas through a nanocomposite membrane while being stretched uniaxially or biaxially is analyzed to better understand the effect of deformation on gas permeation. Second, preliminary work involving the modeling of mass transport through nanocomposite membranes for controlled drug delivery will be presented.
