胶体分散体中分子间相互作用的重要性

Importance of molecular interactions in colloidal dispersions

R. Lopez-Esparza, M. A. Balderas Altamirano, E. Pérez, A. Gama Goicochea

摘要:

我们简要地回顾了胶体分散体的概念,它们的一般性质和它们的一些最重要的应用,以及基本的分子相互作用,引起他们的平衡性能。同样,我们重新讨论了布朗运动和流体动力学相互作用与胶体分散体的粘度的概念。有人认为,使用现代的研究工具,如计算机模拟,可以通过解决大量粒子的分子相互作用的相对简单的模型,准确地预测一些宏观上可测量的性能。最后,作为一个案例研究,我们报告的预测流变性能的聚合物刷使用最先进的,粗粒度的计算机模拟,这是非常符合实验。

英文摘要:

We review briefly the concept of colloidal dispersions, their general properties and some of their most important applications, as well as the basic molecular interactions that give rise to their properties in equilibrium. Similarly, we revisit Brownian motion and hydrodynamic interactions associated with the concept of viscosity of colloidal dispersion. It is argued that the use of modern research tools, such as computer simulations, allows one to predict accurately some macroscopically measurable properties by solving relatively simple models of molecular interactions for a large number of particles. Lastly, as a case study, we report the prediction of rheological properties of polymer brushes using state of the art, coarse grained computer simulations, which are in excellent agreement with experiments.
