Explore the complex thermodynamic behavior of charged diblock copolymer rings in this 27-minute conference lecture from the Workshop on "Charged Soft Matter: Bridging Theory and Experiment." Examine how polymer catenanes - interlocked circular polymer rings - fluctuate in ion solutions that screen long-range Coulomb interactions, building upon the foundational work of L.Tubiana et al. published in Physical Review Letters. Discover the multiple phase transitions exhibited by these catenanes, with particular focus on two identified transitions that correspond to different relevant scales: the individual ring level and the catenane system as a whole. Learn about the dual-scale nature of these systems and how thermodynamic properties emerge from the interplay between single ring dynamics and collective catenane behavior. Gain insights into simulation results for simple chainmail structures composed of up to forty interlocked rings, providing a bridge between theoretical predictions and computational modeling of these complex charged soft matter systems.
