Research Keywords

Polymer、Rubber、Fracture Mechanics、Strain induced crystallization

Overview of Research

Natural rubber (NR, cis 1.4. polyisoprene) accounts for more than 50% of the world’s total rubber consumption. With considering recent importance of sustainability, the importance of NR is expected to increase further in the future. One of the most important feature is strain induced crystallization (SIC) and accompanying strengthening effect. Though wide variety of research for SIC kinetics of NR has been carried out, the essential understanding has not yet been established. Aiming to fundermental understanding of SIC kinetics of NR and its innovative strenghening, comprehensive approach from the viewpoints of polymer synthesis science, polymer physics (especially fracture mechanics), crystallography, and molecular dynamics are carring out.

Message

Polymer science looks classical field, but there are still many unknowns. I hope that you are interested in the world of polymer science.
