| Outline of Final Research Achievements |
We quantitatively evaluated the structural heterogeneity of elastomers based on complex network to describe the elastic properties. It was determined that a unified parameter with topological and spatial information universally describes some parameters related to the stresses. This approach enables us to uncover the role of individual crosslinking points for the stresses, even in complicated structures. By analyzing the weighted network structure of elastomers, we found that how the centrality of each node changes during elongation was significantly affected by the concentration under which crosslinking reaction was carried out. We attempted to quantify the shape of various metastable morphologies of microphase separation in block copolymers that can be observed in a computer simulation. We showed that the size of the largest connected component and the indicators relating to the multifractal analysis were strongly correlated with the free energy of the metastable structures.
