Summary on Grant Application Form
The proposed research will utilise the ease with which polymeric materials may be confined to a thin film geometry to study the effects of confinement on the dynamics of glass forming materials. By measuring the glass transition temperature and relaxation dynamics of both polymer films supported by substrates as well as free standing and embedded polymer films for a variety of systems, we will first of all be able to determine the universality of previously reported effects. In addition we will describe these universal aspects of the data in a context which is compatible with measurements of dynamics in non polymeric confined glass forming systems. Dielectric relaxation studies will be used to study effects on relaxation dynamics in systems where anomalies in the Tg value have been observed and relaxation dynamics of the polymer surface will be studied to check for consistency with the measured Tg values and the properties of the free surface inferred from a modelling of anomalous Tg values.
