Gas transport properties in waterborne polymer nanocomposite coatings containing organomodified claysGas transport properties in waterborne polymer nanocomposite coatings containing organomodified clays Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-142014enNanostructured composite coatings, consisting of phylosilicates embedded within polymer matrices, were prepared and characterized. Waterborne acrylic and polyurethane resins were employed as matrix, and hydrophilic or organically modified nanoparticles of montmorillonite as reinforcement. Emphasis in this article is put on the preparation of the coating. An overview of the major steps involved is presented. The choice of a suitable solvent for the preparation stage is based on the values of the solubility parameters of the constituents. The characterization techniques that are used include X-ray diffraction analysis, gas permeation measurements, and IR spectroscopy. The results highlight the significance of the selection of appropriate ingredients and the knowledge of the interactions between the clay particles, the organic matrix, and the solvents used for the preparation of the coating.http://creativecommons.org/licenses/by/4.0/Journal of Coatings Technology and Research116899-911 Gotsis Alexandros Γκοτσης Αλεξανδρος Choudalakis Georgios Χουδαλακης Γεωργιος Stratigaki Maria Στρατηγακη Μαρια Springer Verlag Nanocomposite coating Clay Exfoliation Gas diffusion Solubility Permeability
