Název v původním jazyce

Gas barrier properties of nanocomposites based on in situ polymerized poly(n-butyl methacrylate) in the presence of surface modified montmorillonite

Popis výsledku v původním jazyce

Barrier membranes were produced by the in situ polymerization of n(butylacrylate) in the presence of surface modified natural montmorillonite. Organoclay with anchoring monomer was prepared via ion exchange reactions of montmorillonite with (acryloyloxy)ethyl alkylammonium cations. The second stage of the process comprised of the in situ polymerization of n-butyl methacrylate and the unsaturated acryloxy ethyl groups anchored on the surface of the clay. Resulting membranes were characterized in terms of their microstructure and diffraction (XRD), their thermal properties (TGA and DSC), and gas permeation properties. The resulting exfoliated morphology led to a decrease in gas permeability. Gas barrier properties of the nanocomposites were compared tothose predicted by phenomenological models such as those of Cussler and Nielsen.
