Abstract

We present a brief review on the effect of phase transitions on liquid crystal colloids. The paper focuses on the evolution of dipolar, quadrupolar and boojum colloids and the ensuing elastic distortions of the director field across phase transitions between various phases, including N, SmA, SmC and N*. The role of pre-transitional and post-transitional elasticity on the resulting defect structure is discussed. Our review includes the results of structural transitions of two-dimensional colloidal assemblies due to the transformation of the defects across the phase transitions. Finally, we discuss some future perspectives on further studies.

相变对液晶胶体的影响

本文简要评述了相变对液晶胶体的影响。本文重点研究了偶极、四极和boojum胶体的演化，以及在不同相（包括N、SmA、SmC和N*）之间的相变过程中导向矢场的弹性畸变。讨论了过渡前和过渡后弹性对缺陷结构的影响。我们的综述包括由于缺陷在相变中的转变而引起的二维胶体组件的结构转变的结果。最后，我们讨论了进一步研究的一些前景。
