We have conducted molecular dynamics simulations in which we investigte how different polymer topologies: (linear diblock, linear triblock, branched and cyclic) of poly(methyl acrylate)-poly(ethylene oxide) block polymers affect their self-assembly, which ultimately results in physical differences in between these micelles. In doing so, we combine graph theory and machine learning (dimension reduction and clustering) techniques to gain a unique insight into the self-assembly process of these different topology polymer molecules. With this detailed description of the structure of these micelles, we have the foundations for topology-based rational design of self-assembled polymeric nanoparticles.
