Rheology of liquid crystalline materials: flow-structure relationships at local and mesoscopic scales studies by novel experimental andtheoretical techniques

Objective



The rheological behaviour of different classes of liquid crystals, namely duration of the project. Presuming an average post-doc period of 18 months main- and side-chain liquid crystalline polymers and the liquid crystals for a young researcher, 16 young scientists will be trained in highly of surfactant/water systems will be investigated. Flow-induced morphological changes and their relaxation will be studied in real-time qualified teams.
during shear and extensional flow by direct optical methods (birefringence and microscopy), dielectric spectroscopy, scattering (light, x-ray and neutron), and magnetic resonance both in the absence and presence of electric & rheo-nuclear magnetic fields. The observations will be correlated with macroscopic phenomena such as changes in viscosity or normal stress differences.
Theories will be further developped to simulate the evolution of structures and to explain the rheological properties.
The objectives are to identify and explain universal features and differences in the flow behaviour of different classes of liquid crystalline materials and to understand the relationships between molecular structure, sample morphology and flow properties.
This shall lead to guidelines for the processing of these materials and for the development of new functional materials.
