Wed 711:<strong>10</strong>-14:00P5.161Aging phenomena in colloidal depletion gelsTakamichi Terao 11 Gifu university, Yanagido 1-1, 501-1193, Gifu, JapanThe aging dynamics of colloidal depletion gel is investigated by computer simulation. In this study,a numerical approach using the effective pair potential is employed, to avoid the slow convergencein binary mixtures due to cage effect The structural formation of colloidal depletion gels is thenclarified. The mean square displacement (MSD) of each segment in depletion gels by stochasticmolecular dynamic simulations is studied numerically, and it is shown that the MSD obeys apower-law, indicating sub-diffusive behavior of depletion gels. We also observe aging phenomenaof the colloidal depletion gels from intermediate scattering functions. Power-law behavior of acharacteristic time in this system, as a function of a waiting time, is also clarified.161
