Using classical density functional theory, the forces between two cylindrical nanoparticles in a liquid crystal solvent are calculated. Both the nematic and isotropic phases of the solvent are considered. In the nematic phase, the interaction is highly anisotropic. At short range, changes in the defect structure around the cylinders leads to a complex interaction between them. In the isotropic phase, an attractive interaction arises due to overlap between halos of ordered fluid adsorbed on the surfaces of the cylinders.
利用经典密度泛函理论,计算了液晶溶剂中两个圆柱形纳米颗粒之间的力。同时考虑了溶剂的向列相和各向同性相。在向列相中,相互作用是高度各向异性的。在短程范围内,圆柱周围缺陷结构的变化导致它们之间产生复杂的相互作用。在各向同性相中,由于吸附在圆柱表面的有序流体晕圈之间的重叠,产生了吸引相互作用。
