| Research Abstract |
On rheology control of spherical nanoparticle dispersions by associating polymers, we found an optimum ratio of the number of nanoparticles and polymer chains for the gel formation by molecular dynamics simulations. We also found that, by increasing the chain stiffness, the zero-shear viscosity increases, and the shear thickening behavior is enhanced. On elastic properties of nanocomposite gels, we found by coarse-grained molecular simulations that the molecular origin of the high extensibility of the nanocomposite gels is the dissociation of polymers from clay particles by uniaxial elongation.
