The simultaneous ingress of acetone and water into dried PVOH-clay nanocomposites containing 2.5 wt% or 5 wt% of well dispersed Na-Cloisite, using FTIR-ATR, has been compared with that into pure PVOH films. The rate at which water and acetone moved through the PVOH films is significantly reduced (i) at high acetone concentrations and (ii) when clay is incorporated in the PVOH film. For example, it...
Polymer-clay nanocomposites have been prepared by solution intercalation of poly(vinyl alcohol) (PVOH) into Na + Montmorillonite (Na + Cloisite ( R)). XRD has been used to determine the dispersion of the individual clay platelets in the PVOH matrix. ATR-FTIR has been used to perform in situ diffusion experiments of water and acetone into nanocomposite films. The data has been...
