Compression properties of individual micron-sized acrylic particles

Abstract: Compression behaviours of individual micron-sized acrylic particles have been studied by using a nanoindentation-based method with a flat-end tip, instead of a commonly used sharp tip. The effect of loading rate on the mechanical properties of the high monodisperse acrylic particles, such as K-value, breaking force and breaking displacement, has been investigated. A wide range of loading rate conditions has been applied to examine the sensitivity of selected mechanical properties. It has been observed that the loading rate has a significant effect on K-value and breaking force whereas breaking displacement is independent of loading rate. These results facilitate the industrial applications of acrylic particles. [Copyright &y& Elsevier]
