	1	Effect of poly(vinyl pyrrolidone)on the morphology and physical properties of poly(vinyl alcohol)/sodium montmorillonite nanocomposite films显示文摘Nanocomposites of poly(vinyl alcohol)(PVA),poly(vinyl pyrrolidone)(PVP) and sodium montmorillonite(Na^+MMT) were prepared by solution mixing and then cast into films.X-ray diffraction analysis and images of transmission electron microscopy establish the formation of PVA/Na^+MMT intercalated nanocomposite.Exfoliated and highly intercalated PVA/PVP/Na^+MMT nanocomposite formed in the presence of PVP.Inclusion of PVP in PVA/Na^+MMT matrix enhances the hydrogen bonding interactions between PVA and Na^+MMT and thus increases the mechanical properties and thermal stability of PVA/PVP/Na^+MMT nanocomposites compared to PVA/Na^+MMT nanocomposite.The interactions between PVA,PVP and Na^+MMT were established by the Fourier transform infrared spectroscopy.The moisture absorption tendency of both the PVA and PVA/PVP films reduced after the incorporation of Na^+MMT at 75%constant relative humidity.Differential scanning calorimetry studies show that the presence of PVP and Na^+MMT both are responsible for reducing the heat of fusion,and crystallinity of PVA.The flow behavior of the PVA,PVA/PVP and its nanocomposite solutions has been also studied.Water vapor permeability of PVA/PVP/Na^+MMT composite films decreased in the presence of nanoclay due to increasing tortuous paths for diffusion.
