Title

Concentration induced size and shape changes in ionic microgel systems

Abstract

We use ionic microgel particles as model systems to understand interactions and phase behavior of soft colloids. To obtain precise information about the size and shape of individual particles, needed in the work on deriving the interaction potential, we propose to carry out small angle neutron experiments using the zero average contrast method. This will allow us to suppress intermolecular interaction contributions to the scattering intensity and only study the form factor in highly concentrated and interacting microgel systems.
