Summary on Grant Application Form |
|
We will make steady and oscillatory shear and extensional flow measurements on aqueous surfactant mesophases (lamellar, gel, hexagonal and cubic) for homologous series of pure non-ionic and cationic surfactants. Concurrently, measurements will be made of the flow-induced aggregate orientation and defect formation within the mesophase, using diffraction, optical and spectroscopic techniques. This will include the development of a flow cell for use in multi-nuclear NMR spectroscopy. Subsequently we will study mixed non-ionic surfactants and ionic/non-ionic surfactant mixtures. From these results we will develop models relating mesophase rheology to aggregate structure and dimensions, and hence to surfactant type. Parallel studies will be carried out on commercial surfactant products. The results will be used to improve current processing procedures and to reduce the time required for developing processing methods for new formulations. The improved understanding will also assist in the design of new products for rapid dissolution and dispersion.
