We show that colloidal superstructures could be assembled in mixtures of large and small colloidal particles dispersed in a nematic liquid crystal. Using elastic interaction of small colloidal particles with the disclination lines we succeed to demonstrate how one can decorate with small particles a topological matrix of defect rings and loops formed by an array of large colloidal particles. Our simulations show that this concept of colloidal self-assembly in nematics could be extended down to the nanoscale particles.
我们表明，在分散于向列型液晶中的大小胶体颗粒混合物中，可以组装胶体超结构。利用小胶体颗粒与位错线的弹性相互作用，我们成功地证明了如何用小颗粒装饰由大胶体颗粒阵列形成的缺陷环和环的拓扑矩阵。我们的模拟表明，这种向列型胶体自组装的概念可以扩展到纳米级颗粒。
