摘　　要：回顾了微纳米碟状胶体的研究发展近况,侧重于合成、自组装和它们在软凝聚态物质及材料科学中的角色.首先讨论了各种合成碟状胶体的方法,包括选择性表面活性剂吸附下的纳米晶体生长、受控沉淀、剥离层状结构化合物、液晶乳液形状变化等等.介绍了这些碟状胶体颗粒在液晶相的形成和悬浮液流变性质等方向的研究应用.特别要提到的是碟状颗粒-聚合物纳米复合材料,如尼龙黏土混合材料、α-ZrP-环氧树脂等在先进功能材料工程中的广泛应用,以及研究人体红细胞的流动性质和形变性质对医疗研究的重大意义.It reviews discotic colloids sized from nanometers to micrometers with attention devoted to the synthetic colloidal disks, their assembly, and their roles in soft condensed matter and material science. Various strategies have been utilized to synthesize discotic colloids, including nanocrystal growth via selective surfactant adsorption, controlled precipitation, exfoliation of layered structure compounds, shape changing of liquidcrystal emulsions. These disks have been employed to study liquid crystalline phase formation and suspension rheology. Diskpolymer nanocomposites, such as Nylonclayhybrid （NCH） and αZrPepoxy, have wide applications in advanced functional material engineering. A special attention is drawn on the human red blood cells （RBC） for the research of its flow and deformation towards medical benefits.
