Liquid-crystalline polymer particles prepared by classical polymerization techniques are receiving increased attention as promising candidates for use in a variety of applications including micro-actuators, structurally colored objects, and absorbents. These particles have anisotropic molecular order and liquid-crystalline phases that distinguish them from conventional polymer particles. In this minireview, the preparation of liquid-crystalline polymer particles from classical suspension, (mini-)emulsion, dispersion, and precipitation polymerization reactions are discussed. The particle sizes, molecular orientations, and liquid-crystalline phases produced by each technique are summarized and compared. We conclude with a discussion of the challenges and prospects of the preparation of liquid-crystalline polymer particles by classical polymerization techniques.
通过经典聚合技术制备的液晶聚合物颗粒作为有前途的候选材料，在包括微致动器、结构色物体和吸收剂在内的各种应用中受到越来越多的关注。这些颗粒具有各向异性的分子排列和液晶相，这使它们有别于传统聚合物颗粒。在这篇微型综述中，讨论了通过经典悬浮聚合、（微）乳液聚合、分散聚合和沉淀聚合反应制备液晶聚合物颗粒的方法。总结并比较了每种技术所产生的颗粒尺寸、分子取向和液晶相。我们最后讨论了通过经典聚合技术制备液晶聚合物颗粒所面临的挑战和前景。
