Partitioning Law of Polymer Chains into Flexible Polymer Networks
Haruki Takarai, Takashi Yasuda, Naoyuki Sakumichi +1
The equilibrium partitioning of linear polymer chains into flexible polymer networks is governed by intricate entropic constraints arising from the configurational degrees of freed…
Universal Negative Energetic Elasticity in Polymer Chains: Crossovers among Random, Self-Avoiding, and Neighbor-Avoiding Walks
Nobu C. Shirai, Naoyuki Sakumichi
Negative energetic elasticity in gels challenges the conventional understanding of gel elasticity; despite extensive research, a concise explanation remains elusive. In this study,…
Polymer Network Diffusion in Charged Gels
Shoei Sano, Takashi Yasuda, Takeshi Fujiyabu +2
The swelling kinetics of charged polymer gels reflect the complex competition among elastic, mixing, and ionic contributions. Here, we used dynamic light scattering to investigate…
Analytical Expression for Fracture Profile in Viscoelastic Crack Propagation
Hokuto Nagatakiya, Naoyuki Sakumichi, Shunsuke Kobayashi +1
We derive an analytical expression for the strain field during steady-state crack propagation in viscoelastic solids described by the standard linear solid (Zener) model. This expr…
Phantom-Chain Simulations for the Effect of Node Functionality on the Fracture of Star-Polymer Networks
Yuichi Masubuchi, Yuya Doi, Takato Ishida +5
The influence of node functionality (f) on the fracture of polymer networks remains unclear. While many studies have focused on multi-functional nodes with f>4, recent research sug…
Universality of Osmotic Equation of State in Star Polymer Solutions
Takashi Yasuda, Masanobu Ino, Takamasa Sakai +1
We experimentally measure the osmotic pressures of linear polymers and three-, four-, and eight-arm star polymers in a good solvent via membrane osmometry. These results reveal tha…
