Thermal, rheological and barrier properties of waterborne acrylic nanocomposite coatings based on boehmite or organo-modified montmorillonite
No full textAn organo-modified montmorillonite (Cloisite®30B) or an unmodified boehmite (Disperal®40) have been added to two acrylic latex dispersions (one of them UV-curable) for obtaining nanocomposite coatings. X-ray diffraction and transmission electron microscopy show a high degree of exfoliation in the nanocoatings based on montmorillonite, together with the deagglomeration of the micrometer sized boehmite powder and the presence of single boehmite crystallites within the polymer matrix. Such morphologies are found to enhance the thermal and thermo-oxidative stability of the latexes and to significantly decrease their oxygen permeability, as wel
