Reverse-Selective Diffusion in Nanocomposite Membranes [PDF]

Physical Review Letters, 2006
The permeability of certain polymer membranes with impenetrable nanoinclusions increases with the particle volume fraction (Merkel et al., Science, 296, 2002). This intriguing observation contradicts even qualitative expectations based on Maxwell's classical theory of conduction/diffusion in composites with homogeneous phases.
