Title:

Monte Carlo Simulation Study of Polyelectrolyte-like Worm-like Micelles

Recently, charged worm-like micelles (WLM) (giant aggregations of surfactant molecules) have attracted additional interest because they show some features very similar to polyelectrolytes. The problem with most polyelectrolytes is their weak scattering power when performing neutron or light scattering experiments, which makes it almost impossible to produce data with a sufficient accuracy over the required range of scattering vector, at low concentrations, where single-coil properties can still be resolved. In contrast, charged wormlike micelles have a much higher scattering power due to their much bigger sizes. For this reason charged WLM in solution has been proposed as a model system for polyelectrolytes. In this talk we focus on Monte Carlo simulations of charged WLM with particular emphasis on the scattering functions and on scaling properties of such systems.
