Small water droplets dispersed in a nematic liquid crystal exhibit a novel class of colloidal interactions, arising from the orientational elastic energy of the anisotropic host fluid. These interactions include a short-range repulsion and a long-range dipolar attraction, and they lead to the formation of anisotropic chainlike structures by the colloidal particles. The repulsive interaction can lead to novel mechanisms for colloid stabilization.
分散在向列型液晶中的小水滴表现出一类新型的胶体相互作用，这种相互作用源于各向异性主体流体的取向弹性能。这些相互作用包括短程排斥和长程偶极吸引，它们会导致胶体颗粒形成各向异性的链状结构。排斥相互作用可导致胶体稳定化的新机制。
