| The work is devoted to developing a method for producing nanocomposite based on polyvinyl alcohol (PVA) and montmorillonite intercalated with polyvinylpyrrolidone. The structure and thermal characteristics of nanocomposites were investigated by X-ray diffraction analysis and differential scanning calorimetry. The modification of PVA with intercalated montmorillonite reduces the degree of crystallinity of the resulting nanocomposites but significantly increases their thermal stability. Under ultrasound, the intercalated montmorillonite was completely distributed in a PVA solution and formed a monocrystalline structure. The method of obtaining structured, water-insoluble nanocomposite films based on PVA is also developed in work. Films based on PVA with modified montmorillonite were cross-linked at 110 ºC in the presence of 5 wt.% acrylic acid and 0.5 wt.% Ferrous (II) sulfate as an initiator. The formed films have a homogeneous cross-linked structure. The influence of borax, the content of intercalated MMT, and solution pH on the rheological properties of PVA-based compositions have been established. |
