Semidilute Principle for Gels
Naoyuki Sakumichi, Takashi Yasuda, Takamasa Sakai
Polymer gels such as jellies and soft contact lenses are soft solids consisting of three-dimensional polymer networks swollen with a large amount of solvent. For approximately 80 y…
Damageless Tough Hydrogels with On-demand Self-reinforcement
Chang Liu, Takeshi Fujiyabu, Naoya Morimoto +5
Most tough hydrogels are reinforced by introducing sacrificial structures that can dissipate input energy. However, since the sacrificial damages cannot recover instantly, the toug…
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…
