软复合物活性微流变中的不连续变薄

Discontinuous Thinning in Active Microrheology of Soft Complex Matter

R. Wulfert, U. Seifert, T. Speck

摘要:

采用理论和数值模拟,我们证明了不连续的力变薄由于外部探头在主机介质中,我们近似为无结构的运动。当探针的驱动超过临界力时,介质的微粘度突然下降约一个数量级。这种现象发生在探针和足够密集的宿主介质之间的强吸引相互作用。

英文摘要:

Employing theory and numerical simulations, we demonstrate discontinuous force thinning due to the motion of an external probe in a host medium, which we approximate as structureless. When the driving of the probe exceeds a critical force, the microviscosity of the medium drops abruptly by about an order of magnitude. This phenomenon occurs for strong attractive interactions between probe and a sufficiently dense host medium.
