Summary on Grant Application Form |
|
We plan to study the phase behaviour and interfacialproperties of confined liquid mixtures, primarily using polyolefins of controlled chain architecture as model liquids and a thin film geometry to provide confinement. Advnaces in polymer synthesis allow us to make pairs of polymers with precisely controlled molefular weight and thermodynamic interaction, while neutron reflectivity allows us to characterise internal interfaces within the thin films with sub-nanometer resolution. An experimental program is planned which will allow us to answer fundamental questions about the phase behaviour of confined liquid mixtures. These include how the width of the interface depends on the distance from critically both in situations where mean field theory is likely to be accurated and hwnen b7ulk compostion fgluctuations are improtand, how the interface is modified by interfacial fluctuations and how these flucturations are themselves modifiedin confined systems by long-range and truncation forces, how surface fields affect the structure of the films, and how equilibrium is reached when the system is prepared in non-equilibrium state and allowed to evolve.
