Polymer Structure in Elastic turbulence.
Building on a recent successful ILL experiment, we aim to characterise the conformation and structure of a very high molecular weight polymer in aqueous solution under static and under shear conditions. This material undergoes elastic turbulence (i.e. an unusual form of turbulent flow at low Reynolds numbers) for which the underlying polymer structure is not known. The previous experiment completely changed how we visualise the polymer conformation and we now wish to complete this revised picture. The aqueous polyacrylamide solution is typically 10-100 times above its overlap concentration and therefore the reptation time is on the minute scale or even slower. This gives rise to non-linear rheology, e.g. elastic turbulence. By using in situ rheo-SANS we will be able to access the underlying molecular structure of the polymer chains.
