| Outline of Final Research Achievements |
Empirical research work was performed to elucidate an origin of anomalous viscoelastic properties of natural rubber with nanomatrix structure of proteins; that is, higher the frequency, the lower the mechanical energy dissipation in rubbery plateau region. Relationship between the viscoelastic properties and the nanomatrix structure formed by dispersing natural rubber particles into the nanomatrix of the proteins was investigated by using model elastomer with the nanomatrix structure. It was found that the anomalous viscoelastic properties of natural rubber with the nanomatrix structure were attributed to a combination of entropic elasticity of rubber and energetic elasticity of the nanomatrix.
