In this work we present a study of the local structure of a model colloidal suspension highly confined inside a cylindrical pore. Such a study is based in Monte Carlo computer simulations, using the repulsive part of the Derjaguin-Landau-Verwey-Overbeek potential as the pair interaction between particles. The structural properties calculated here are the concentration profile n(rho), the axial pair correlation function g(z), and the axial-angular pair correlation function g(z,straight phi). The behavior of these quantities is analyzed as a function of the density of colloidal particles in the restricted space, and as a function of the size of the pore.
在这项工作中，我们展示了对高度受限在圆柱形孔隙内的模型胶体悬浮液局部结构的研究。这样的研究基于蒙特卡罗计算机模拟，使用Derjaguin-Landau-Verwey-Overbeek势的排斥部分作为粒子间的对相互作用。这里计算的结构性质包括浓度分布n(ρ)、轴向对关联函数g(z)以及轴向-角向对关联函数g(z,φ)。分析了这些量随受限空间中胶体颗粒密度以及孔隙尺寸的变化情况。
