A rheo-SANS study of the correlation between elastic strain and alignment in polymer-like systems
We propose to develop a generic procedure for rheo-structure studies using a well-studied polymer-like viscoelastic micellar solution. Within this proof-of-concept study, we will link the elastic extension of a viscoelastic fluid to the well-defined alignment factor used to describe polymer-like and wormlike systems. The experiments are carried out in the 1-2 and 1-3 planes of shear, providing structural links to the shear and normal stresses. By mapping out the elastic strain and comparing it to the alignment of the micellar segments, we will be better able to produce a tensorial stress-SANS rule, forming an intimate relationship between structure and the rheology of soft matter systems.
