A theory for the effect of patch / non-patch attractions on the self-assembly of patchy colloids

Abstract

In this paper, we develop a thermodynamic perturbation theory to describe the self-assembly of patchy colloids which exhibit both patch-patch attractions as well as patch / non-patch attractions. That is, patches attract other patches as well as the no patch region. In general these attractions operate on different energy scales, which allows for controlled self-assembly as well as anomalous phase behavior. As an application we apply the model to the study of liquid water.
