We modify the Hayter-Penfold formalism and gave a quantitative analysis to fit the viscosity of rod-like micelles solutions under shear using measured small-angle neutron scattering (SANS) intensity. The original formalism is applicable to a dilute solution, but we found that the theory can fit our measured results excellently if we use the effective viscosity of the solution in place of the solvent viscosity of the original formalism. The fittings yielded good values just the same as our experiment results.

Combining neutron scattering and fully atomistic molecular dynamics simulations allows unraveling structural and dynamical features of polymer melts at different length scales, mainly in the intermolecular and monomeric range. Here we present the methodology developed by us and the results of its application during the last years in a variety of polymers. This methodology is based on two pillars: (i) both techniques cover approximately the same length and time scales and (ii) the classical van Hove formalism allows easily calculating the magnitudes measured by neutron scattering from the simulated atomic trajectories. By direct comparison with experimental results, the simulated cell is validated. Thereafter, the information of the simulations can be exploited, calculating magnitudes that are experimentally inaccessible or extending the parameters range beyond the experimental capabilities. We show how detailed microscopic insight on structural features and dynamical processes of various kinds has been gained in polymeric systems with different degrees of complexity, and how intriguing questions as the collective behavior at intermediate length scales have been faced.
