Abstract

We describe the elasticity of compressed microgel suspensions starting from a core–shell model for single particles. The mechanical properties of the inner core and of the outer corona are described via the mean field Flory theory and via the Alexander–de Gennes model for polymer brushes, respectively. The model successfully reproduces experimental measures of the elastic shear modulus up to a constant factor that we rationalize in the jamming perspective.
