Complexity of micelle formation as studied by a minimum particle-based model — •Simon Raschke and Andreas Heuer — Institute of Physical Chemistry, WWU Münster, Correnstr. 28/30 48149 Münster, Germany

The formation of self assembled structures such as micelles has been intensively studied and is well understood. The ability of a solution of amphiphilic molecules to develop micelles is depending on the concentration and characterized by the critical micelle concentration (cmc), above which micelle formation does occur. We developed a minimalistic coarse grained model for amphiphilic molecules in the continuum and simulated the time evolution via dynamic Monte Carlo simulations in the canonical (NVT) ensemble. This approach enables long timescales and allows studying of related processes. The model is also capable of simulating the frame-guided assembly process [1], which makes vesicle formation into a predefined frame possible and reliable below cmc. Equilibration in the cmc domain turns out to happen on very long timescales and the cluster formation is highly non trivial. We discuss the influences of local energies, curvature, frame-guides and disorder and their connection to the processes of cluster formation.
