Outline of Final Research Achievements |
The toughening mechanism of slide-ring materials, in which polymer chains are cross-linked by ring molecules, has been investigated by macroscopic fracture tests and microscopic structural analysis. For slide-ring gels with solvent, their network structure is homogenized by the sliding of the movable cross-links under deformation, and the fracture toughness is dominated by the sliding distance of the sliding cross-links. In the case of sliding elastomers without any solvent, the ring cross-links are dispersed homogeneously in the elastomers and the homogeneous network structure leads to their high stretchability.
