Dynamic hierarchical structure of polymers governs the macromolecular properties that do not characterize smaller molecules. Our research aims to add novel functions to polymer materials through the understanding and controlling of the polymer dynamics. We are also developing environmental polymer materials based on a concept of carbon cycle.

Polymers with Dynamic Bonds :

Polymers extended by dynamic covalent bonds and supramolecular polymers dynamically change their size and structure through scission, rebinding and exchange of dynamic bonds. By designing the dynamic nature, we are developing various functions including self-healing, shape memory and thermo-responsive hard-soft conversion for smart materials.

Nanostructure Fabrication by Controlled Non-equilibrium Freezing :

Micro- and nano-ordered patterns are developed in polymer thin film by using dynamic structuring process such as self-assembly, phase separation, and dissipative structure formation.

Biobased Polymers :

Novel biobased functional polymers are obtained from furan compound which is easily available from wood biomass.
