Objectif The aim of this project is to analyse, both theoretically and experimentally, the anisotropic relaxation functions inherent to heterophase materials (e.g. incompatible blends) as well as homophase individual polymeric melts and solutions. One can distinguish the following steps in the project:- Constructing and improving experimental devices for the direct measurement of 2D dependencies of the storage and loss dynamic moduli as a function of frequency under small-amplitude oscillating shear in different directions superperimposed on steady shear flow. The mechanical tests will be supported by direct observation of morphology evolution of polymer blends;- An appropriate selection of the materials under consideration, including individual polymer solutions; lyotropic and thermotropic blends of incompatible polymers; liquid precursors of nanocomposites; associative polymers and amphiphilic block-copolymers;- Joint investigations of the "morphology-anisotropic rheology" relationships for selected systems, comparison of results obtained by different methods and initiation of general physical explanations for the phenomena observed;- Creation of rheological constitutive equations both on the phenomenological and a molecular basis for the description of anisotropic viscoelastic functions keeping in mind thermodynamically stipulated anisotropy (LC systems), anisotropy of dispersed phase droplets and orientation of fillers particles. Generation of calculation methods of anisotropic relaxation spectra and their comparison with experimental data;- Preparation of final products from blends of thermoplastics, blends containing an LC component, thermoplastics filled by anisodiametric particulate particles, and measurement of their anisotropic mechanical characteristics with subsequent interrelation with the rheological behaviour during processing.
