Dynamics and viscoelastic behavior of waterborne acrylic polymer/silica nanocomposite coatings

The dynamics and linear viscoelastic response of waterborne acrylic/silica nanocomposite coatings have been studied. In-situ nanostructured latex were prepared using emulsion polymerization in semi-batch mode and contained up to 3 wt% nanosilica of 7 nm diameter [Romo-Uribe et al., Europ. Polym. J. 2016, 76, 170–186]. High-resolution transmission electron microscopy (HRTEM) of the coatings demonstrated well-dispersed nanoparticles at low silica...
