摘要
单分散胶粒是食品、印染、陶瓷、光学胶片和电磁流变体等材料的主要成分,其三维有序组装结构被通称为胶态晶体。具有三维周期性结构的胶态晶体在光电研究领域具有特殊意义。以胶态晶体为模板可复制获得结构上与其三维周期性结构反相的新型功能性介孔材料。后者兼具固体材料本身和长程周期有序结构两种特性,是当前光电领域急需的光子晶体的最佳候选。本文综合阐述了单分散胶粒、胶态晶体以及具有三维周期性有序结构的材料的制备、性质和初步及潜在应用。
Monodispersed colloidal latex is the main component of the food,optical film and electric and magnetorheological fluids.They could assemble to the periodic ordered construct that is called col-loidal crystal.With three-dimensional ordered periodic structure,it is quite important in the photoelec-trical industry.Apart from model of microlithography and senor of environmental examination,the col-loidal crystal has been wildly used as template to synthesize various functional macroporous materials with the anti-phrase structure of the colloidal crystal.The macroporous material with high reflection in-dex is the proper candidate for the photonic crystal since it holds the merits of both functional charac-ter of solid and periodic ordered macroporous structure.In this paper,the fabrication,properties,current and potential applications of the monodispersed latex,colloidal crystal and other ordered peri-odic materials are summarized.
