Abstract

AbstractCurrently, intense research is underway to develop polymer nanocomposites because of their numerous potential applications. However, the uniform dispersion of inorganic nanoparticles in polymer nanocomposites without an additional chemical phase has proved to be a difficult challenge. In this paper, we present our results that ultrasonic cavitation could be an effective tool to disrupt agglomerates, thus forming well‐dispersed inorganic phase polymer nanocomposites. This is especially true if polymer degradation could be minimized during ultrasonic processing. Our results suggest that better dispersion of nanoparticles achieved via ultrasonic cavitation not only improved the elastic modulus of the polymer nanocomposites but also enhanced the stress at 5% strain values.
