Around the topological defects of a liquid crystal, there are gradients of the director distortions and the orientational order, where a long range elastic force field is created. When polymers are placed in the field, an attractive force along the gradient, toward the defect core, is imposed to the particles. By this long-range force, the particles are migrated and finally trapped by the defect. The polymer-stabilized liquid crystal blue phases, which show fast electro-optic effect are stabilized by this kind of effect. Recent research progresses on the related phenomena are briefly reviewed in this paper.
