| Outline of Final Research Achievements |
We introduced controlled heterogeneity in Tetra-PEG gel, which has homogeneous network structure, and attempted to evaluate them separately. As a result, it was suggested that the Tetra-PEG gels fabricated at the overlapping concentration have uniform network structures, Their elastic moduli obeyed the phantom model, and the fracture energy can be described by the Lake-Thomas model. It was suggested that the influence of the heterogeneous distribution of the sub-chain length and that of the dangling chain is not significant as the heterogeneity. On the other hand, the influences of the entanglement and the loop are detected as the deviation between the model prediction and the experimental values. These results may help understand the fundamental physical properties of polymer network.
