Summary on Grant Application Form |
|
The project will involve experimental and theoretical studies of particle dynamics, phase separation kinetics and rheology, in a model colloid-polymer mixture. Experimental techniques will include direct microscopic observation in which 3-D images are automatically constructed from 2-D slices, static and dynamic light scattering, and rheometry. Two main themes will be emphasised. First the mechanisms and kinetics of the separation of the mixtures into regions of both two-phase (colloidal fluid + colloidal crystal or colloidal gas + colloidal liquid) and three-phase (colloidal gas + liquid + crystal) co-existence will be studied. Theoretically the challenge is to understand phase separation in the presence of competing processes, eg gas-liquid separation and crystallisation. Another emphasis will be on understanding long-lived metastable gels states of colloid-polymer mixtures which temporarily arrest phase separation. Second, a recently suggested connection between particle dynamics, measured by light scattering, and frequency-dependent rheology will be investigated and, hopefully established.
