Size polydispersity in colloidal systems is often treated as a problem to be minimized. It is known that in highly polydisperse systems, crystallisation in colloidal suspensions is suppressed and with low colloid polydispersity, the colloid-polymer mixtures display the same phase behaviour as the in the monodisperse case. I will talk about some recent experimental work on colloid-polymer mixtures using colloids with a polydispersity of 6% and the effect this polydispersity has on the phase diagram.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
