摘要
利用Gay-Berne模型,结合分子动力学模拟方法,研究了粒子长径比对椭球粒子液晶行为的影响,考察了粒子长径比对向列相和近晶相的影响.结果表明,长径比相对较小的粒子有利于向列相的形成,而长径比相对较大的粒子更有利于近晶相的形成.分析了近晶相和向列相形成的动力学过程.
The Gay-Berne model and molecular dynamics simulation method was used to study the influences of aspect ratio on the liquid crystal behaviors of ellipsoidal particles, especially focusing on nematic and smectic phases. The results indicated that the ellipsoids with a relatively small aspect ratio favor the formation of nematic phases, while the ellipsoids with a relatively large aspect ratio prefer the formation of smectic phases . Furthermore, the formation processes of the nematic and smectic phases in detail were analyzed. The results provide theoretical guidance for designing different types of liquid crystals and understanding the formation mechanism of liquid crystal.
