Multi-chain Slip-spring Model for Entangled Polymer Dynamics
Takashi Uneyama, Yuichi Masubuchi
It has been established that the entangled polymer dynamics can be reasonably described by single chain models such as tube and slip-link models. Although the entanglement effect i…
Crossover Time in Relative Fluctuations Characterizes the Longest Relaxation Time of Entangled Polymers
Takashi Uneyama, Takuma Akimoto, Tomoshige Miyaguchi
In entangled polymer systems, there are several characteristic time scales, such as the entanglement time and the disengagement time. In molecular simulations, the longest relaxati…
Concentration Dependence of Rheological Properties of Telechelic Associative Polymer Solutions
Takashi Uneyama, Shinya Suzuki, Hiroshi Watanabe
We consider concentration dependence of rheological properties of associative telechelic polymer solutions. Experimental results for model telechelic polymer solutions show rather…
Detailed Balance Condition and Effective Free Energy in the Primitive Chain Network Model
Takashi Uneyama, Yuichi Masubuchi
We consider statistical mechanical properties of the primitive chain network (PCN) model for entangled polymers from its dynamic equations. We show that the dynamic equation for th…
Single Chain Slip-Spring Model for Fast Rheology Simulations of Entangled Polymers on GPU
Takashi Uneyama
We propose a single chain slip-spring model, which is based on the slip-spring model by Likhtman [A. E. Likhtman, Macromolecules, 38, 6128 (2005)], for fast rheology simulations of…
Anisotropic Mobility Model for Polymers under Shear and its Linear Response Functions
Takashi Uneyama, Kazushi Horio, Hiroshi Watanabe
We propose a simple dynamic model of polymers under shear with an anisotropic mobility tensor. We calculate the shear viscosity, the rheo-dielectric response function, and the para…
Equilibrium Statistics of Weakly Slip-Linked Gaussian Polymer Chains
Takashi Uneyama, Kazushi Horio
We calculate the free energy and the pressure of a weakly slip-linked Gaussian polymer chains. We show that the equilibrium statistics of a slip-linked system is different from one…
Study of thickness dependent density in ultrathin water soluble polymer films
Mojammel H. Mondal, M. Mukherjee, K. Kawashima +2
Density of the polyacrylamide ultrathin films has been studied using X-ray reflectivity technique. Two sources (one powder and another aqueous solution) of polyacrylamide were used…
Onion structures induced by hydrophilic and hydrophobic ions in a binary mixture
Koichiro Sadakane, Akira Onuki, Koji Nishida +2
Phase transition is observed between one-phase disordered phase and an ordered phase with multi-lamellar (onion) structures in an off-critical mixture of DO and 3-methylpyridin…
