Mechanical Properties of Nanocomposite Latex Films via Instrumented Indentation



Aaron M. Forster, Stephanie S. Watson, Laura Johnson, Li Piin Sung


Inorganic particles, introduced into networked or glassy polymer films, have been used to increase the stiffness of films as a function of pigment loading. Latex films often contain inorganic pigments to increase the opaqueness of the film and to act as UV absorbers. The interaction of the inorganic fillers with the latex spheres is much different than the interaction of a particle with a networked or glassy polymer matrix. In this research, the influence of particle size (nm mm), particle type (TiO2, MgO, and ZnO), and particle volume concentration (0 % - 17.8 %) on the mechanical properties of the coating are investigated.
