Structural Evolution in Dense Dispersions and Colloidal Composites

建议研究颗粒间短程表面力对致密胶体分散体的长程微观结构和结构转变的影响。静态和动态光散射、X射线散射和视频显微镜的结果将使用统计力学理论和逆散射理论进行解释。实验中将考虑固定分散和剪切分散。将分析胶体化学和微流体动力学对结构变化和流变性的影响。如果成功，这项研究将在陶瓷、表面活性剂和聚合物悬浮液方面有广泛的应用。

It is proposed to study the effect of inter-particle short range surface forces on the long range microstructures and structural transition in dense colloidal dispersions. Results of static and dynamic light scattering, X-ray scattering and video-microscopy will be interpreted using statistical mechanical theory and an inverse-scattering theory. Stationary and sheared dispersions will be considered in experiments. The effects of colloidal chemistry and microhydrodynamics on the structural changes and rheological properties will be analyzed. If successful, the research will have a broad range of applications related to ceramic, surfactants and polymeric suspensions.
