Self-assembly in magnetic filament systems: impact of internal factors — •Elena Pyanzina, Tatjana Belyaeva, Marina Kashpurova, and Ekaterina Novak — Ural Federal University, Lenin av. 51, 620000, Ekaterinburg, Russia

The fundamental understanding of the self-assembly properties of colloidal systems is one of the key topics in current research on novel microstructured soft materials and technologies. In this work we investigate self-assembly of magnetic filaments of different topology with different additional interaction and particles polydispersity. We performed molecular dynamics simulations using a Langevin thermostat. Cluster analysis based on graph theory is used to analyze the obtained data. At the moment we are analyzing the results, but we can already say that the introduction of additional attraction and particles polydispersity significantly expands the structural diversity of the self-assembly of magnetic filaments, and the effect of magnetic dipole-dipole interaction remains substantial. All these results will pave the way for the development of analytical models and identify the most interesting building block candidates for the design of new magnetoresponsive materials.
