Gas Permeability of Polymer/2D-Nanofiller Nanocomposites: Structural Interpretation and Nanoeffects

This paper presents a structural model that provides an accurate description of gas permeability in polymer/2D-nanofiller nanocomposites. We observed a higher efficiency in reducing gas permeability for nanocomposites compared to microcomposites. This effect stems from strong interfacial interactions in nanocomposites, leading to a higher content of impermeable interfacial regions. We also estimated the maximum reduction in gas permeability at a fixed nanofiller content.
