Percolation induced gel-gel phase separation in a dilute polymer network

Shohei Ishikawa, Yasuhide Iwanaga, Takashi Uneyama +8

Cosmic large-scale structures, animal flocks, and living tissues are non-equilibrium organized systems created by dissipative processes. Despite the uniqueness, the realization of…

Temperature Dependence of Polymer Network Diffusion

Takeshi Fujiyabu, Takamasa Sakai, Ryota Kudo +4

The swelling dynamics of polymer gels are characterized by the (collective) diffusion coefficient of the polymer network. Here, we measure the temperature dependence of of…

Tri-branched gels: Rubbery materials with the lowest branching factor approach the ideal elastic limit

Takeshi Fujiyabu, Naoyuki Sakumichi, Takuya Katashima +4

Unlike hard materials such as metals and ceramics, rubbery materials can endure large deformations due to the large conformational degree of freedom of the crosslinked three-dimens…

Universal equation of state describes osmotic pressure throughout gelation process

Takashi Yasuda, Naoyuki Sakumichi, Ung-il Chung +1

The equation of state of the osmotic pressure for linear-polymer solutions in good solvents is universally described by a scaling function. We experimentally measure the osmotic pr…

Negative energy elasticity in a rubberlike gel

Yuki Yoshikawa, Naoyuki Sakumichi, Ung-il Chung +1

Rubber elasticity is the archetype of the entropic force emerging from the second law of thermodynamics; numerous experimental and theoretical studies on natural and synthetic rubb…
