Reversible networks
Reversible networks made by macromolecules or small molecules exhibit unique visco-elastic properties. We are investigating the rheology of associating polymer networks on the basis of molecular models.

Distribution of loops in networks
We are studying the topological structure, i.e., distribution of loops in networks, and how they affect network visco-elasticity. |

Nonlinear elasticity and swelling of entangled gels
Entangled gels exhibit nonlinear elasticity under either uniaxial or biaxial deformations. We study effects of entanglements and how they contribute on nonlinear elasticity of polymer networks. We are developing theory of swelling and de-swelling of entangled gels.
